Genesis Plus GX is able to accurately emulate various console hardware models, which makes it compatible with 100% of SG-1000, Master System, Game Gear, Genesis / Mega Drive & Sega/Mega CD released software, including demos, unlicensed & pirate games.
|
||||
|
||||
This means that all these games have been verified to be working without any graphical glitches or lock-up but off course, it is impossible for me to test all games *from start to end* so feel free to report an [issue](https://bitbucket.org/eke/genesis-plus-gx/issues?status=new&status=open) if you found a specific game not running accurately with this emulator.
|
||||
|
||||
On a side note, make sure you are always using good dumps: ROM files labeled as bad, "fixed" or hacked dumps (b1, f1, h1, ...), are known to cause issues, even on real hardware.
|
||||
|
||||
## Sega/Mega CD games ##
|
||||
|
||||
Sega/Mega CD games are only compatible with Genesis / Mega Drive hardware. Sega/Mega CD add-on is automatically enabled when a valid CD image file is detected.
|
||||
|
||||
|
||||
## Genesis / Mega Drive games ##
|
||||
|
||||
Genesis / Mega Drive games are only compatible with Genesis / Mega Drive hardware. Some games might require different hardware to be enabled (PICO games or games only working with CD unit attached) and are auto-detected.
|
||||
|
||||
|
||||
## Game Gear games ##
|
||||
|
||||
Game Gear games are only compatible with Game Gear hardware.
|
||||
|
||||
|
||||
## Master System games ##
|
||||
|
||||
Master System games are compatible with Game Gear and Genesis hardware, using backwards compatibility mode. However, the following games are known to be working only on specific hardware:
|
||||
|
||||
### _games requiring Master System BIOS to initialize VDP registers_ ###
|
||||
* California Games II
|
||||
* Speed Ball
|
||||
|
||||
### _games incompatible with Genesis VDP_ ###
|
||||
* Bart vs. The Space Mutants (palette issue)
|
||||
* Earthworm Jim (zoomed sprites issue)
|
||||
* X-Men - Mojo World (palette issue)
|
||||
|
||||
### _games requiring legacy VDP modes (not supported by Genesis VDP or Game Gear with custom BIOS)_ ###
|
||||
|
||||
* Dr Hello
|
||||
* F-1 Spirit - The way to Formula-1
|
||||
* F16 Fighter
|
||||
* F16 Fighting Falcon
|
||||
* FA Tetris
|
||||
* Flashpoint
|
||||
* Loretta no Shouzou - Sherlock Holmes
|
||||
* Penguin Adventure
|
||||
* Street Master
|
||||
* Super Boy II
|
||||
* The Three Dragon Story
|
||||
* Wonsiin
|
||||
* Cyborg Z
|
||||
|
||||
### _games requiring extended VDP modes (Master System II & Game Gear only)_ ###
|
||||
* Cosmic Spacehead
|
||||
* Excellent Dizzy Collection, The [Proto]
|
||||
* Fantastic Dizzy
|
||||
* Micro Machines
|
||||
|
||||
### _games requiring original VDP limitation (Mark III & Master System I only)_ ###
|
||||
* Y'S (Japanese version)
|
||||
|
||||
|
||||
## SG-1000 games ##
|
||||
|
||||
SG-1000 games are compatible with Mark-III and Master System hardware, using backwards compatibility mode (a custom BIOS, not available, is required on Game Gear). In order to display the correct colour palette, it is however recommended to use SG-1000 hardware.

** _The emulator does not start and hangs on a black screen when loaded on my Wii._ **
|
||||
|
||||
Preferably use the Homebrew Channel to launch this program on your Wii, using the provided meta.xml file.
|
||||
|
||||
If you installed the emulator as a standalone channel or are using a different loader, you might have modified or deleted required system files (IOS), which could prevent the application from starting. Also note that some loaders are not compatible with compressed dols, instead of provided boot.dol, use genplus_wii.dol, which is not compressed.
|
||||
|
||||
Lastly, if you have unsupported devices connected to the Game Cube ports or USB ports, you might want to remove them.
|
||||
|
||||
----
|
||||
|
||||
** _The emulator loads fine but randomly freeze (no input response) or crashes (DSI exception screen) in the menu or during game._ **
|
||||
|
||||
Use the latest version of Homebrew Channel to launch the emulator.
|
||||
|
||||
----
|
||||
|
||||
** _When I try to load game files from my SD card or USB drive, no files are found or an error message occurs._ **
|
||||
|
||||
Make sure you have at least one FAT (FAT16 or FAT32) partition on your device.
|
||||
|
||||
----
|
||||
|
||||
** _My USB2 compatible drive does not seem to be detected, is that normal ?_ **
|
||||
|
||||
USB2 compatibility requires IOS58 to be installed in your system (it usually came with recent System Menu updates). You must also make sure the Homebrew Channel is using this IOS (reinstall HBC if it doesn't) to load the emulator.
|
||||
|
||||
Please note that you cannot use both USB ports at the same time.
|
||||
|
||||
----
|
||||
|
||||
** _I can not load game files from the DVD, an error message occurs saying it can not be mounted or no valid DVD was found._ **
|
||||
|
||||
First, make sure the DVD has been formatted in the expected format (ISO9960/Joliet). Then, your console must be able to read burned DVD: on a non-chipped Wii, you should use the Homebrew Channel and the provided meta.xml file, which enables full access to the DVD drive, without requiring a modchip.
|
||||
|
||||
Please note that on most recent Wii models, it is impossible to enable DVD access anymore.
|
||||
|
||||
----
|
||||
|
||||
** _Well, I can access my device but I can't see all my game files, what is happening ?_ **
|
||||
|
||||
Because of memory limitations, the emulator only lists up to 1000 game files per directory. This should be more than enough for anybody but if you have a larger "collection", it is highly advised to arrange your files within subdirectories, which also increase the speed and the usability of the file browser.
|
||||
|
||||
----
|
||||
|
||||
** _When I load a game, nothing happen. I can return to the emulator menu but the game does not play or make the emulator crash._ **
|
||||
|
||||
You probably tried to load an unsupported game file. The emulator only supports valid Genesis / Mega Drive (.bin, .gen, .md, .smd, .mdx), Master System (.sms), Game Gear (.gg), SG-1000 (.sg) ROM files or Sega/Mega CD image files (.bin, .iso, .cue). ROM files (not CD image files !) can be zipped but make sure there is only one file per .zip archive. Also note that .rar or .7z files are NOT supported.
|
||||
|
||||
Lastly, make sure you are only using verified dumps: bad dumps, hacked or fixed image files are subject to crash, even on real hardware, so just get ride of them.
|
||||
|
||||
----
|
||||
|
||||
** _I'm trying to load a CD game but I got an error message telling me the file is too big_ **
|
||||
|
||||
This happen if the file you are trying to load is not recognized as a valid Sega / Mega CD image. Please make sure you are only loading valid .iso or .bin files (or a .cue file pointing to a valid .iso / .bin file). Compressed image (such as .rar, .zip, .7z, etc) are NOT supported for CD emulation, you must decompress them first. Also make sure the game you are trying to load is really a Sega / Mega CD game (you wouldn't believe the amount of people trying to load Saturn games !)
|
||||
|
||||
----
|
||||
|
||||
** _I can hear the sound of the game I loaded but nothing is displayed but a black or distorted screen._ **
|
||||
|
||||
You are most likely using invalid video settings. Try deleting the configuration file (config.ini) and restart the emulator. If that does not help, try changing the following options, Display and TV Mode, and see if that fixes the issue.
|
||||
|
||||
----
|
||||
|
||||
** _I try to load a CD game but there is no audio at all, only sound effects most of the time._ **
|
||||
|
||||
It means you did not load a CD image with valid CD-DA tracks informations. You can confirm that by entering the CD Boot menu when resetting the game (press A to enter Boot menu) and seeing the number of tracks is stuck to 99 (max). Keep in mind that if you are using an ISO file with external audio files, only 44100hz stereo 16-bit WAV or OGG audio files are supported and you must either name them accordingly or use an associated CUE file. When using a BIN file, an associated CUE file is needed if you want to hear audio tracks. Have a look in the README for more details about supported CD image & audio tracks format and how you should load them. Also note that many games will lock or crash at some points if the expected number and lengths of audio tracks is not respected.
|
||||
|
||||
----
|
||||
|
||||
** _Well, I can hear audio tracks and the CD Boot menu show them all but the sound is buggy/scratched/distorted._ **
|
||||
|
||||
It is most likely due to audio files themselves. Play them on a computer with another media player to check if there are correct. Many CD rips you can find online are either corrupt or incomplete, you might want to use verified good disc dumps.
|
||||
|
||||
----
|
||||
|
||||
** _When playing CD games, I randomly experiment some slowdowns or short freezes with audio and/or video._ **
|
||||
|
||||
Sega/Mega CD emulation is quite CPU consuming and all in all, there is only short time allowed to the emulator to read data from the disc image. Since disc images are continuously accessed from the loading device (SD, USB, DVD), slow or inconsistent device accesses will likely cause bottlenecks in emulator processing. There is no much solutions beside using faster devices and, for USB drives, to make sure IOS58 is loaded when the emulator starts and USB2 mode is enabled.
|
||||
|
||||
----
|
||||
|
||||
** _How can I use my Classic Controller, Nunchuk, etc ? It is connected to my Wii Remote but it does not respond in games._ **
|
||||
|
||||
You must first configure the type of controller you want to use for each player. Go to controller settings, pick one of the player and change the affected device. Don't forget to change it back if you disconnect the expansion controller.
|
||||
|
||||
----
|
||||
|
||||
** _How can I play with the gun in Snatcher ? I successfully calibrated it using the wiimote when the game is started but it does not aim correctly during the game_ **
|
||||
|
||||
The calibration routine in Snatcher is kinda bugged, or more exactly, it worked with a real gun because the original Justifiers were relatively imprecise so you wouldn't really notice if it doesn't really aim the center of the screen. The solution is simply not to use the calibration option AT ALL, the default configuration works fine in-game and aims perfectly where the wiimote is pointing.
|
||||
|
||||
----
|
||||
|
||||
** _My second Wii remote controller is not detected by the emulator. How can i play 2 players games ?_ **
|
||||
|
||||
Any additional Wii remote must be permanently registered in your Wii system settings, otherwise it cannot be detected by homebrew applications. Go back to the Wii system menu and register each Wii remote using the red SYNC buttons, as explained in your Wii user manual.
|
||||
|
||||
----
|
||||
|
||||
** _I'm trying to use ??? feature and have put all the required files as described in the User Manual but it doesn't seem to work. What am I doing wrong ?_ **
|
||||
|
||||
Make sure you disable the "Hide Known Extension" feature in your OS then verify again if the required files have the proper name and extension.
|
||||
|
||||
----
|
||||
|
||||
** _How can I play 32X games in this emulator ?_ **
|
||||
|
||||
You can't. This program currently only emulates SG-1000, Master System, Game Gear, Genesis / Mega Drive & Sega/Mega CD hardware, including existing backward compatibility modes. Other systems might be added in the future but it's actually not high priority.
|
||||
|
||||
----
|
||||
|
||||
** _Hey, I have a very original idea. What about adding a cool feature like (insert anything) ? I think the emulator would be perfect with that feature_. **
|
||||
|
||||
You can always make an enhancement request in the Issue page on this site. However, if something has not been implemented yet, it has very likely a good reason not to be. Some stuff need time to work on, while others are simply no interest to me. As a general rule, I prefer focusing myself on the emulation core rather than features only designed to make the emulator interface "cooler" or "easier" to use.

## How to start the emulator ##
|
||||
|
||||
Gamecube and Wii applications usually come in the form of .dol files.
|
||||
|
||||
Once you have downloaded and decompressed the archive, you should get two versions of the emulator:
|
||||
|
||||
* genplus_cube.dol is the application running in Gamecube mode.
|
||||
|
||||
This can be loaded on a Game Cube by using various methods: see http://www.gc-linux.org/wiki/Getting_Started#Booting_Code for more details.
|
||||
|
||||
* genplus_wii.dol is the application running in Wii mode.
|
||||
|
||||
The easiest way to run the emulator on a Wii is to install the [Homebrew Channel](http://hbc.hackmii.com/). Once you are done, simply copy the /apps directory (included with this release) and its content to the root of your SD card or USB drive.
|
||||
|
||||
There are other ways to run dol files on the Wii like building a dedicated channel or using an alternate DOL loader. Feel free to visit http://www.wiibrew.org for additional information.
|
||||
|
||||
----
|
||||
## How to use the emulator ##
|
||||
|
||||
Genesis Plus GX supports Mega Drive / Genesis, Master System, Game Gear & SG-1000 ROM files and Sega/Mega CD image files. Supported ROM files must come in the form of RAW .bin, .ison .gen, .md, .smd, .mdx, .sms, .gg & .sg files. Compressed .zip files (for ROM files only) are also supported as long as they contain a single ROM file in one of the supported format.
|
||||
|
||||

To play a game, you first need to load a ROM file from one of the supported devices: you can either load it from DVD, SD card or USB drive (Wii only).
|
||||
|
||||
|
||||
There is a limit of 1000 ROM files per directory so it's strongly advised to create subdirectories. Reducing the number of ROM files per directory also improves menu interface speed and usability.
|
||||
|
||||
|
||||
For Sega / Mega CD emulation, original BIOS files are needed for each console region: the emulator expects BIOS ROM files to be respectively named BIOS_CD_J.bin, BIOS_CD_U.bin and BIOS_CD_E.bin and placed in /genplus/bios/ directory on the default FAT device. It should not matter what BIOS versions you are using but it is recommended, for best compatibility, to use Model 1 BIOS ROM image files.
|
||||
|
||||
### from SD ###
|
||||
|
||||
The SD card should be formatted to FAT (FAT16 or FAT32). If not found, the emulator automatically creates a directory named “/genplus” at the root of your SD card, as well as subdirectories required by the emulator to store miscellaneous files (cheat, save & screenshot files).
|
||||
|
||||
|
||||
By default, the emulator will look for files in the sd:/genplus/roms directory but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device.
|
||||
|
||||
|
||||
### from USB (Wii only) ###
|
||||
|
||||
The USB drive should have at least one partition formatted to FAT (FAT16 or FAT32), other file systems (NTFS, EXT2, etc) are not supported. If no SD card is inserted when the emulator starts, it automatically creates a directory named “/genplus” at the root of your USB drive partition, as well as subdirectories required by the emulator to store miscellaneous files (cheat, save & screenshot files).
|
||||
|
||||
|
||||
By default, the emulator will look for files in the usb:/genplus/roms directory but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device and for each file types.
|
||||
|
||||
|
||||
To use an USB2 drive, you must have IOS58 installed (it should be automatically installed with System Menu 4.3 update). You should also load the emulator through the Homebrew Channel, using the provided meta.xml file and make sure Homebrew Channel is using IOS58 as default IOS. If not, you might need to reinstall Homebrew Channel after having installed IOS58.
|
||||
|
||||
|
||||
### from DVD ###
|
||||
|
||||
The DVD should be formatted using ISO9660/Joliet (refer to the user manual of your DVD Burning software for more details). The Game Cube Mini-DVD drive allows up to 1.35GB of data while the Wii DVD drive allows up to 4.7GB of data (simple-layer).
|
||||
|
||||
|
||||
By default, the emulator will look for files at the root of your DVD but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device and for each file types.
|
||||
|
||||
|
||||
To use DVD on a non-chipped Wii, you should load the emulator through the Homebrew Channel and use the provided meta.xml file, in order to allow full access to the DVD drive.

Genesis Plus GX is an open-source Sega 8/16 bit emulator focused on accuracy and portability. Initially ported and developped on Gamecube / Wii consoles through [libogc / devkitPPC](http://sourceforge.net/projects/devkitpro/), this emulator is now available on many other platforms through various frontends such as:
|
||||
|
||||
* [Retroarch (libretro)](http://www.libretro.com)
|
||||
|
||||
* [Bizhawk](http://tasvideos.org/Bizhawk.html)
|
||||
|
||||
* [OpenEmu](http://openemu.org/)

The source code, originally based on Genesis Plus 1.2a by [Charles MacDonald](http://www.techno-junk.org/ ) has been heavily modified & enhanced, with respect to initial goals and design, in order to improve emulation accuracy as well as adding support for extra peripherals, cartridge or console hardware and many other exciting [features](https://bitbucket.org/eke/genesis-plus-gx/wiki/Features).
|
||||
|
||||
The result is that Genesis Plus GX is now more a continuation of the original project than a simple port, providing very accurate emulation and [100% compatibility](https://bitbucket.org/eke/genesis-plus-gx/wiki/Compatibility) with Genesis / Mega Drive, Sega/Mega CD, Master System, Game Gear & SG-1000 released software (including all unlicensed or pirate known dumps), also emulating backwards compatibility modes when available. All the people who contributed (directly or indirectly) to this project are listed on the [Credits](https://bitbucket.org/eke/genesis-plus-gx/wiki/Credits) page.

Multi-platform sourcecode (core) is available for use under a specific non-commercial [license](https://bitbucket.org/eke/genesis-plus-gx/src/aa9d0889309bc8b13f140be8949415a32d0461a7/LICENSE.txt) and maintained here as well as [github](https://github.com/ekeeke/Genesis-Plus-GX) so that other Genesis Plus ports can take advantage of it, as I really hope this emulator can become a reference for _open-source_ and _accurate_ Genesis emulation. If you ported this emulator to other platforms or need help porting it, feel free to contact me.
