Update buttonMappingChanger.htm
Updated to support the new May 15th firmware. Also took the opportunity to make a few tweaks, including presenting the button tables in a more standard "ABXYLR" order, regardless of the byte-order in the actual SF2000 data files

<h1>Data Frog SF2000 Button Mapping Tool</h1>
|
||||
<p>This tool lets you alter the button mappings for the SF2000 hand-held console; it can generate per-game mappings, as well as alter the global mappings defined in the device's <code>bisrv.asd</code> BIOS file. As the SF2000 supports multiplayer gaming via an optional wireless controller (sold separately), mappings for both Player 1 and Player 2 are possible. Please note this tool is provided as-is, and no support will be given if this corrupts your device's BIOS; make sure you have backups of anything you care about before messing with your device's critical files! 🙂</p>

<p>This tool lets you alter the button mappings for the SF2000 hand-held console; it can generate per-game mappings, as well as alter the global mappings defined in the device's <code>bisrv.asd</code> BIOS file or in the <code>KeyMapInfo.kmp</code> file used by newer BIOS versions. As the SF2000 supports multiplayer gaming via an optional wireless controller (sold separately), mappings for both Player 1 and Player 2 are possible.</p>

<p> Please note this tool is provided as-is, and no support will be given if this corrupts your device's BIOS or keymap file; make sure you have backups of anything you care about before messing with your device's critical files! 🙂 Also note that per-ROM mappings are only possible on firmwares prior to the May 15th firmware.</p>
