There was a lot of repeated JS across all my tools (e.g., image conversion, BIOS hash checking, etc.), and so I decided to move all shared code out to its own separate library. This will improve scalability and maintainability at the cost of portability - a fair trade in my opinion. This work also involved large-scale refactoring of all of the tools. There's no actual functional difference (all the tools should behave exactly the same), bar some UI improvements for the oldest tools as a result of moving to the same codebase used by the more recent tools.

<h1>Data Frog SF2000 Save State Tool</h1>
|
|
<p>The SF2000 supports save states for games, but it bundles the save state data into a custom format including a thumbnail and metadata; this bundle can't be directly used as save state data for other emulator platforms (e.g., Retroarch). This tool allows you to extract raw save-state data and thumbnails from SF2000 save-state bundles, in case you want to use them with the same emulator on another device; it also allows you to take save states from another device, and convert them to a format the SF2000 can parse. Please note this tool is provided as-is; make sure you have backups of anything you care about before potentially replacing any files on your SF2000's microSD card! 🙂</p>
|
|
<p>This tool makes use of the <a href="https://github.com/nodeca/pako">pako</a> JavaScript library.</p>

<h2>Step 1: Select Operating Mode</h2>
|
|
<p>This tool can operate in two main modes - you can use it to convert save states <em>from</em> the SF2000 format <em>to</em> raw save-state data (and optionally download the thumbnail), or you can use it to convert raw save state data <em>from</em> another emulator <em>to</em> the SF2000 format. Choose the mode you want, and follow the next instruction that appears.</p>

html = "<section id=\"processUserFile\"><h2>Step 3: Select Game ROM And Slot Number</h2><p>To name your new SF2000 save state properly, this tool needs to know two things - the name of the game ROM file the save state is for, and which save slot (1, 2, 3 or 4) the save state should take up. Use the controls below to select your game ROM file from your SF2000's microSD card, and to choose which save slot you want.</p><p>When you've chosen a ROM file and a slot number, the Download button will become enabled, and can be used to download your new save state file. Put it in the <code>save</code> subfolder along-side wherever your ROM file is stored on the SF2000's microSD card (e.g., if your ROM file is <code>sd:/ROMS/Apotris.gba</code>, and you chose save slot 1, you'd put the resulting save state in <code>sd:/ROMS/save/Apotris.gba.sa0</code>).</p><p>The one special case is with arcade games; the ROM you need to select is one of the ones in the <code>sd:/ARCADE/bin/</code> folder, and the resulting save state bundle goes into <code>sd:/ARCADE/save/</code>. As an example, if you wanted to transfer a save state to the SF2000 for the game \"Metal Slug\" in slot 3, you'd select <code>sd:/ARCADE/bin/mslug.zip</code> and Slot 3, and the final location to put the save state would be <code>sd:/ARCADE/save/mslug.zip.sa2</code> - I hope that makes sense! You can <a href=\"https://vonmillhausen.github.io/sf2000/arcade/DataFrog_SF2000_FBA.html\" target=\"_blank\" rel=\"noreferrer noopener\">find a list of all potential arcade zip-file names and the full name of the game they represent here</a>, if it helps - the first column (\"rom\") is the name of the zip-file without the <code>.zip</code> part, and the second column (\"fullname\") is the full name of the game/romset.</p><div id=\"step3Messages\"></div>";
