Refactored the CFW FAQ to make the hcRTOS and multicore efforts more distinct. Refactored the shortcuts FAQ to mention Tadpole first (easier for most folks). Refactored the slow SNES FAQ in light of 1.71. Refactored the quiet A/V output FAQ to suggest firmware updating first. Added details about the new 1.71 firmware version to the Firmware and Resources sections, and did a lot of little edits throughout the doc as well to standardise on Data Frog's version numbering (seems to be what most folks refer to). Added a note that the permanent bootload bugfix only needs to be applied once per device. Added another modification example to the analysis of `Foldername.ini` courtesy of `wyverino`.

So is the "Data Frog" any good? Only you can answer that question for yourself. There are certainly more powerful devices out there, more fully featured devices, devices with better hardware, etc. - but almost all of those devices cost a lot more than the SF2000. At the end of the day, you have to look at the features offered at the given price-point, and only then can you decide if you're interested in the device or not.
### Is there any custom firmware?
As of October 12th 2023, **no**, not yet; however efforts are underway. While an SDK for the CPU has been identified, the developers working on custom firmware have generally reached the conclusion that the SDK is unfinished and of low quality. While it has been used to produce experimental builds of Retroarch, demonstrating various game systems operating on the SF2000, there are notable problems - core features like video and audio drivers are missing (and thus would have to be developed from scratch), and overall system stability is very low. Additionally, most of the experimental system builds had audio and/or video performance issues, and most also caused the SF2000 to run "hot", which may impact the lifespan of the device. [A GitLab repo](https://git.maschath.de/ignatz/hcrtos) has been set up by `ignatzdraconis` for the work based on this SDK.
As of October 19th 2023, **no**, not yet. Two main efforts have been made:
Most recently, a new tack is being tried by the development team - they're trying to modify the stock SF2000 firmware to add additional functionality. Theoretically, this would come with the benefit of having audio and video drivers already built, providing no worse performance than stock firmware, while providing features like support for additional emulated systems. An experimental developer build has been produced which demonstrates additional systems like Atari 2600 and PC-Engine running under the stock firmware. [A GitLab repo](https://gitlab.com/kobily/sf2000_multicore) has been set up by `kobil` for the work on modifying the stock firmware.
#### hcRTOS (true CFW)
Earlier this year, an SDK for the CPU in the SF2000 was been identified. Theoretically, this would allow a full custom firmware to be built and compiled for the device. The developers working on custom firmware spent some considerable time and effort working on porting Retroarch (as it seemed like it would be the quickest route to a custom firmware with support for many systems), however they ran into several problems. It appears that the SDK was unfinished and of low quality - core features like video and audio drivers were missing (and thus had to be developed from scratch), and overall system stability of the produced builds very low. When crashed happened with running cores (which was frequently) no useful debugging information was produced, and so tracking down the source of issues became a major time-sink. Additionally, most of the experimental builds when they did work had audio and/or video performance issues, and most also caused the SF2000 to run "hot", which would likely have impacted the lifespan of the device and thus are not recommended for usage beyond a few minutes at a time. [A GitLab repo](https://git.maschath.de/ignatz/hcrtos) was set up by `ignatzdraconis` for the work based on this SDK, however work on developing a full custom firmware using this SDK has been parked for now.
You can follow along with discussion in the [`Retro Handhelds` Discord server](https://discord.gg/retrohandhelds) (specifically, in the `🐸data_frog_sf2000` channel there's a `SF2000 Dev` thread where most of the tech talk and details are posted first).
#### Multicore (modified stock)
More recently, a new tack is being tried by the development team - they're trying to modify the stock SF2000 firmware to add additional functionality. Theoretically, this would come with the benefit of having audio and video drivers already built (the contractors producing the stock firmware for the SF2000 have access to these), providing no worse performance than stock firmware, while also providing features like support for additional emulated systems. An experimental developer build called the "multicore" build has been produced which hijacks the stock Game Boy Advance emulator to run additional systems like Atari 2600 and PC-Engine, some stand-alone engines for games like Doom and Cave Store, as well as alternatives for some of the stock emulators already included with the SF2000. Some of the new systems appear to run at full speed; some run without sound or with less than full speed, and others don't work at all yet. [A GitLab repo](https://gitlab.com/kobily/sf2000_multicore) has been set up by `kobil` for the work on modifying the stock firmware.
**Note:** Any non-stock firmwares currently built for the SF2000 should be considered **highly** experimental, and are not vetted to be "safe" to run (e.g., current builds may push the hardware of the SF2000 to its operational limits do to optimisation issues, and may incur thermal damage to the device if left running for too long, etc.). Such builds are not intended for day-to-day usage yet; if you're waiting for safe custom firmware to be available, keep waiting - the current experimental builds are not ready for prime-time yet.
You can follow along in real time with the development discussion in the [`Retro Handhelds` Discord server](https://discord.gg/retrohandhelds) (specifically, in the `🐸data_frog_sf2000` channel there's a `SF2000 Dev` thread where most of the tech talk and details are posted first).

### How do I change the four shortcuts/games listed on each system's main menu page?
Answer: with a fair bit of work! The _images_ for the shortcuts are baked into each system's main menu background image - check out the ["Images (Used)"](#images-used) section below, and use your browser's search feature to search for `main menu background`, and you'll see what I mean. `Zerter#4954` has created a tool for theme makers which lets you more easily edit these icons, [which you can find here](https://zerter555.github.io/sf2000-collection/mainMenuIcoEditor.html). The _text_ under each shortcut is stored in a separate image - in the `05.22` firmware, the files are `gkavc.ers` if the device's language is set to Chinese, or `gakne.ctp` for all other languages (again, check the details in the ["Images (Used)"](#images-used) section below). Finally, the actual roms that are launched for each shortcut are stored in the `xfgle.hgp` file, which is plain text - you can learn more about it in the ["ROM Lists"](#rom-lists) section below.
Recent versions of [Tadpole](https://github.com/EricGoldsteinNz/tadpole) by `.ericgoldstein` and `jasongrieves_02643` have support for changing the shortcuts if you're looking for an automated way to do things. There's also a separate web-based tool from `Zerter#4954` which lets you edit these icons, [you can find it here](https://zerter555.github.io/sf2000-collection/mainMenuIcoEditor.html).

### SNES games run really slowly... what's wrong?
There's a bug in all stock firmware versions later than the original mid-March firmware which often causes SNES games to run really slowly on first launch (and their sound is slow and lower pitch too); this only impacts SNES. `bnister` discovered that this appears to be related to a firmware bug, in which certain settings (audio rate and clock speed) for the SNES emulator are set _after_ Retroarch has been initialised, causing Retroarch to get confused and run at half rate. `Dteyn` has created a web-based tool which will patch your BIOS with a workaround to correct the issue - [you can find their tool here](https://dteyn.github.io/sf2000/tools/snesEmulatorFix.htm).

This bug was fixed in firmware 1.71, so you can [upgrade to that firmware version](#firmwarebios-bisrvasd) to fix things. If you don't want to upgrade to 1.71, there are two other ways to fix or work-around the issue:
Alternatively, if you don't want to patch your BIOS then you can work around the issue by launching the game, then quitting back to the game selection menu via `START + SELECT`, and then immediately re-launching the game again. Note however that the stock firmwares do also struggle a bit with SNES emulation in general, so any additional slowdown after the second launch is just what you get.

* Quitting back to the game selection menu via `START + SELECT`, and then immediately re-launching the game again will get the game to run at full speed the second time around; this would need to be done at least once every time you power on the SF2000.
Note however that the stock firmware does also struggle a bit with SNES emulation in general, so any slowdown or poor SNES performance you see after addressing the bug is just what you get.

@ -130,18 +137,16 @@ The three most likely causes for this are:
* Your battery could be running low. The SF2000 will still "turn on" when its battery is low on charge (the red light will still come on), but the device itself will actually fail to boot, just leaving you with a black screen. Turn the device off, and charge it fully (the stock battery takes 3.5 hours to charge from empty - the green charging light will not go out, so you'll have to time it yourself).
### When I connect the SF2000 to a TV via the A/V cable, the sound is very quiet/low - is that normal?
It's "normal" for certain versions of the firmware, anyway! Older firmware versions had no issues with audio volume via A/V, but at least the `05.22` version does. `Zerter#4954` from Discord found a workaround:
This was due to a bug in some earlier firmware versions; it was officially fixed in firmware 1.6, so if you're running a prior firmware version ([check here](https://vonmillhausen.github.io/sf2000/tools/firmwareVersionChecker.htm)), you can [upgrade to a newer firmware version](#firmwarebios-bisrvasd).
Alternatively, `Zerter#4954` from Discord found a workaround if you don't want to upgrade:
> when I did this the AV audio work normally: I had to load the game first then plug-in the 2.5mm to rca jack. [...] but when I quit then exit then tried the game again it returns to very low audio. [...] will need to do the work around again
So you can try launching the game first, and _then_ plug in the A/V cable to get full volume on the TV.
Alternatively, the issue was addressed in the `08.03`/`1.6V` firmware, so you could [try updating to that](#firmwarebios-bisrvasd).
### Game saves don't seem to be working for me? Save states are fine, but the built-in save function in games doesn't seem to work?
Unfortunately, correct - with the stock firmware, the built-in save feature of emulated games does not work correctly, and the SF2000 won't store new save data after the first time it's created for a game. If you want to save your progress in a game on the SF2000's stock firmware, use save states instead.
Note that the `08.03`/`1.6V` firmware _appears_ to have fixed this for GBA based on community reports, but not for other emulated systems.

## Hardware
### CPU
Although the main CPU of the SF2000 has literally had it's markings milled off by a routing tool, the community has determined that it's a HCSEMI B210, a single-core MIPS processor running at 810 MHz (or 918 MHz with the `08.03`/`1.6V` firmware). It appears to be a clone of an ALi Tech chip. [An SDK has been found](http://www.zcsd-tech.com//download/content-54.html) for it.

### Display
The SF2000 features a `240x320` IPS display panel (not OCA laminated), which has been rotated 90° clockwise to give a `320x240` display. It demonstrates screen tearing for all emulators, running from the right of the console to the left due to the panel rotation.

Also note that while you can technically charge the SF2000 while it is powered on, doing so using a charger that supports fast charging or power delivery has a high chance of blowing the charging module IC and killing the device (multiple community reports). For safest charging, use a charger that only supports a maximum output of 5v.
The stock firmware's power monitoring system (which controls the battery level indicator on the main menu, along with when the device warns the user about a low battery condition) is poorly calibrated for the stock battery that comes with the device; as such, the SF2000 basically indicates it has a full battery at all times. `bnister` and `dteyn` from Discord worked together to identify the locations within the stock firmware where the calibrations are stored, and determined more appropriate calibration values for the stock battery. `dteyn` wrote a web-based tool which will patch an existing `bisrv.asd` file to use the new values; you can [find their "Data Frog SF2000 Battery Meter Fix" tool here](https://dteyn.github.io/sf2000/tools/batteryMeterFix.htm).

### Default ROMs
The default full firmware for the SF2000 comes with over 6000 ROMs across the seven supported systems. The manual suggests these are for "demonstration purposes" only, and should be deleted by the owner (with any failure to do so not being their responsibility) - despite the fact that the SF2000's menus are hard-coded for this specific list of ROMs. The ROM files themselves are a custom bundle format; the first `59,904 bytes` are an RGB565 image shown as a thumbnail beside the game when selected in a game-list, and the remainder of the file is a slightly mangled/obfuscated ZIP file containing the game's single ROM file. The only exception to this format are the arcade ROMs, which consist of a plain-old Final Burn Alpha ROM zip file, coupled with a `.zfb` file containing the thumbnail image and a pointer to the ROM zip file name.
I was curious to see how the included ROMs matched up against the current "[No-Intro](https://no-intro.org/)" catalogue for each of the non-arcade systems, so I wrote a small script to extract the ROMs from the SF2000's bundles (`05.22` firmware), and compare the hashes against the current (June 9th, 2023) set of No-Intro DAT files. You can [find a big HTML file with all of the results here](/defaultRoms/defaultRomsNoIntroCheck.htm), and [a raw CSV file of the same data here](/defaultRoms/defaultRomsNoIntroCheck.csv). You can click most of the column headers in the HTML version to sort the table by that column. The NES ROMs had their first 16-bytes stripped to remove their "iNES" header (thanks for the tip, `bnister`!), and were compared against the "header-less" No-Intro NES dat file.

The firmware for the SF2000 is actually located on the microSD card, in a file called `bisrv.asd` located in the BIOS folder. This file is a monolithic binary blob, which contains the device's OS, the emulators, their settings... basically everything. Data Frog have issued some firmware updates for the device since launch; the updates have added new features (e.g., additional language support, favourites, history, etc.), but have also introduced bugs (e.g., some SNES games run very slowly until they are quit and launched again, etc.). Data Frog have published a YouTube video showing how to update the firmware on the device, which [you can find here](https://www.youtube.com/watch?v=j8dT2fdGfck); the video's description contains a link to where you can download the latest firmware. Note that Data Frog's official firmware update/reinstallation process involves fully erasing the device's microSD card and replacing its contents with a fresh set of files - this will also erase any user-created files including saves states or user-installed ROMs. You can learn more about save state files and how to back them up in [the Save States section](#save-states).
**WARNING: The latest October 7th/1.7 firmware version has a critical issue with SNES save states; SNES save states are not created correctly, and will hang the device if you attempt to load one created using this firmware version. As such, it is highly recommended that you avoid the October 7th/1.7 firmware version.**

Note that Data Frog's official server for downloading firmware is _very_ slow, with typical transfers taking many hours to complete as their firmware images are full images including ROM files. If you don't care about the stock ROM files, an alternative method for downloading the latest firmware _without_ the ROM files is to use [Tadpole](https://github.com/EricGoldsteinNz/tadpole). Refer to Tadpole's documentation for more information.

| Mid-March | ? | The original firmware that shipped with the first batch of devices |
| April 20th | ? | The first official firmware update; fixed some button mappings for Genesis, added support for 15 new languages. Also partially broke SNES compatibility - many SNES games will run very slowly on first launch, but quitting and immediately re-launching the game will have it run at normal speed (normal for the SF2000, anyway) |
| May 15th | ? | Added a built-in UI for global button mapping (which is broken in several ways, mainly SNES and Genesis controls are swapped, and no support for setting Player 2 controls), added a History feature, added a Favourites feature |
| May 22nd | 1.5V | First firmware with an official version number. Fixed the SNES/Genesis swapped button mappings, and now sets Player 2 controls to be identical to Player 1 (no way to set independently). There's some evidence of undocumented emulation improvements; some GBA homebrew that was non-functional in previous firmwares now loads correctly, and some GBA titles see marginally improved performance |
| August 3rd | 1.6V | The only official release note indicates that the issue with low sound volume when using A/V out was fixed. Aside from that, community members have noticed that the inability of the SF2000 to work with in-game saves appears to have been fixed for GBA (but not other emulators), and that the CPU clock has been changed from 810 MHz to 918 MHz (an overclock); this may be responsible for some community reports of slightly better performance for some games |
| October 7th | 1.7 | No official release notes yet, but there is a new critical bug in SNES save-states - they're not created correctly, and attempting to load one created with this firmware version hangs the device. Other than that, the "have to load SNES games twice" bug appears to have been fixed, although the community has created [a fix for that](#snes-games-run-really-slowly-whats-wrong) for the other firmware versions already |
| May 22nd | 1.5 | First firmware with an official version number. Fixed the SNES/Genesis swapped button mappings, and now sets Player 2 controls to be identical to Player 1 (no way to set independently). There's some evidence of undocumented emulation improvements; some GBA homebrew that was non-functional in previous firmwares now loads correctly, and some GBA titles see marginally improved performance |

| October 7th | 1.7 | The [SNES first-launch speed bug](#snes-games-run-really-slowly-whats-wrong) was fixed, however there is a new critical bug in SNES save-states - they're not created correctly, and attempting to load one created with this firmware version hangs the device. DO NOT USE THIS FIRMWARE VERSION! |
| October 13th | 1.71 | This is a bugfix release - the bug with SNES save states introduced in 1.7 was fixed, so this firmware appears to be stable again. Analysis shows no other significant changes from 1.7 |

It's strongly recommended that you fix the bug on your SF2000, as failure to do so can cause some headaches for you down the road with a non-booting device. There's a couple of ways to go about fixing it:
#### If Your SF2000 Is Currently Able To Boot Normally
If your SF2000 is currently able to boot normally (i.e., when you power it on, you get to the stock main menu), then you can permanently fix the bug in the device's hardware as follows (credit to `bnister` for both finding the root cause for the bug, and creating the permanent fix):

1. Ensure your SF2000 is in a state where it boots normally when turned on (displays a boot logo, proceeds to the stock firmware main menu)
2. Ensure your SF2000's battery is fully charged (having the device power off during the patching process will likely "brick" it, rendering it inoperable)

### Images (Used)
As far as I am aware, all of the below images are actively used by the latest firmware version; happy to take any corrections if it turns out any of them are unused! Note that while the stock theme is based around a `640x480` resolution, the actual _display_ on the SF2000 is a `320x240` one. The OS on the device uses nearest-neighbour scaling for its images, giving the stock UI a somewhat aliased appearance. If you're planning to make your own theme for the SF2000, see my [Notes For Theme Creators](#notes-for-theme-creators) section below for some tips and tricks. I've written a generic image tool for the SF2000 - it lets you convert SF2000-formatted images to PNG files, and lets you convert PNG or JPEG images to SF2000 formats (which may be useful if you want to theme your device); you can [find this tool here](https://vonmillhausen.github.io/sf2000/tools/genericImageTool.htm).

### Images (Unused)
To the best of my knowledge, the following image files are currently __unused__ by the `20230515` firmware, and were probably left over from previous devices (the SF2000 shares a bit of lineage with some USB-stick devices) or development. The images marked "Alternate UI" below appear to have been for a UI where the systems were scrolled through horizontally, and the "shortcut" games for each system were scrolled vertically.

SF2000
@ -550,7 +554,7 @@ And here's my current understanding of what each line is used for:
- `17`: The number of languages supported by the firmware
- `FFFFFF`: Hexadecimal colour (RGB) for the general game-list texts, and the `x/yyy` game count in the top-right corner of each game-list
- `FF8000 ROMS`: The first defined main menu section (the sections that are scrolled vertically on the main menu). Internally they are numbered from 0; so the `ROMS` section (user ROMs and settings) is 0, `FC` (NES) is 1, `SFC` (SNES) is 2, etc.. The `FF8000` is the hexadecimal colour (RGB) to display the text of the currently selected/highlighted game in the list; the default colour is orange. _Side note:_ after the `ARCADE` section, there's two additional `ROMS` sections; the firmware is hard-coded to have ten sections. The SF2000 appears to share its firmware with other similar devices, and some of those devices feature different menu sections (e.g., "CPS1", "Neo Geo", etc.). I suspect that the best of those systems has ten sections in its main menu, which doesn't match up with the eight sections on the SF2000 (seven supported systems + the user ROMs/settings section). As the firmware requires ten sections to be defined, they just repeated the `ROMS` section to fill in the remaining places. Like I say, that's just a guess!
- `8 7 0`: This is used to control the main menu rotation. `8` tells the firmware how many main menu sections are actually in-use on this device; for the SF2000 that's seven supported consoles + the user ROMs/settings section, for eight total. `7` tells the firmware which menu section to default to when the device boots up, which is why by default it always starts in the `ARCADE` section. `0` tells the firmware which section to display the special "user settings" menu on (the one with History, Favourites, TV System, Language, etc.). So for example, if you wanted the SF2000 to start up on the user ROMs/settings screen instead of Arcade, you could change this line to read `8 0 0`

So for example, if you wanted the SF2000 to start up on the user ROMs/settings screen instead of Arcade, you could change this line to read `8 0 0`; or if you wanted the user ROMs/settings screen to be the _only_ screen available (e.g., if you were intending to hand the device to someone unfamiliar with retro emulation, and you wanted to reduce sources of confusion for them), you could set it to `1 0 0` (suggestion from `wyverino`)
- `24 184 144 208`: These numbers control the position and size of the game artwork in each system's game-list. The first two numbers are the X and Y coordinates from the top-left corner of the screen for where to start drawing the artwork; the second two numbers are the width and height of the artwork to draw. Note that the SF2000 doesn't do any image scaling; the dimensions are for the rectangular area the device will begin adding each pixel of the source artwork to. If the artwork's dimensions don't exactly match the dimensions specified here, the artwork will not display properly
- `40 24`: The width and height of the icon shown beside the currently selected/highlighted game in a game-list. Again, these are the dimensions of the rectangular area the SF2000 draws the pixel data into, so if these numbers don't match the dimensions of the list indicator image, the image will not display properly

### Notes For Theme Creators
This section isn't really about the `Resources` files per-se, but it's tangentially related. The fact that the SF2000's UI resources are pulled from the microSD card opens up the door to "theming" the device, which is great. However, if you do decide you want to make a theme for the SF2000, here's a few things I've found that you may want to bear in mind:

## Document Version History
- `20231019 - 1.43`: Refactored [the CFW FAQ](#is-there-any-custom-firmware) to make the hcRTOS and multicore efforts more distinct. Refactored [the shortcuts FAQ](#how-do-i-change-the-four-shortcutsgames-listed-on-each-systems-main-menu-page) to mention Tadpole first (easier for most folks). Refactored [the slow SNES FAQ](#snes-games-run-really-slowly-whats-wrong) in light of 1.71. Refactored [the quiet A/V output FAQ](#when-i-connect-the-sf2000-to-a-tv-via-the-av-cable-the-sound-is-very-quietlow---is-that-normal) to suggest firmware updating first. Added details about the new 1.71 firmware version to the [Firmware](#firmwarebios-bisrvasd) and [Resources](#resources) sections, and did a lot of little edits throughout the doc as well to standardise on Data Frog's version numbering (seems to be what most folks refer to). Added a note that [the permanent bootload bugfix](#if-your-sf2000-is-currently-able-to-boot-normally) only needs to be applied once per device. Added another modification example to the analysis of [`Foldername.ini`](#foldernameini) courtesy of `wyverino`.
- `20231014 - 1.42`: Have now confirmed that no resource files changed with the new October 7th/1.7 firmware, so have updated the tables in the [Resources](#resources) section to reflect this. Also added a reference to `detyn`'s Battery Meter Fix tool to [the FAQ on stuff new SF2000 owners can do](#i-just-got-my-sf2000-what-modding-can-i-do-with-it).
- `20231012 - 1.41`: Added basic information about the new (and critically broken) October 7th/1.7 firmware version to the [Firmware](#firmwarebios-bisrvasd) section (I'm waiting for my official copy to finish downloading before updating the tables in the [Resources](#resources) sections).

- `20230829 - 1.35`: Added a [MicroSD Card](#microsd-card) section to [Hardware](#hardware) to provide some detail about the SF2000's slightly unusual microSD card situation. Added detail about the [Neo Geo Unibios Menu](#neo-geo-unibios-menu) discovery to the [Arcade](#arcade) section (thanks `nanchon18#2262`!). Updated the custom firmware FAQ with the latest details. Updated the "what modding can I do" FAQ to strongly suggest fixing the [bootloader bug](#bootloader-bug) before doing any other modding to the device; also added a note that the Tadpole tool can perform a lot of the modding tasks. Updated the "quiet A/V sound" FAQ with details about the fix in the `08.03`/`1.6V` firmware. Updated the "in game saves don't work" FAQ with details about this apparently being fixed for GBA in the `08.03`/`1.6V` firmware.
