Substantially re-written in light of the May 22nd firmware, which had a `bisrv.asd` of the same length as the May 15th firmware, but different in operation - the byte order in `KeyMapInfo.kmp` has been flipped for SNES and Genesis. As there's no way to tell from just looking at a `KeyMapInfo.kmp` what the byte order should be, users must now provide both `bisrv.asd` AND `KeyMapInfo.kmp` files - the `bisrv.asd` is now hash-checked against known versions, and that's used to inform which byte order to use for the `KeyMapInfo.kmp`

<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 (NOTE: only possible on firmwares prior to the May 15th firmware), 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! 🙂</p>
|
|
<p>This tool was originally written by nikita.burnashev (email) gmail.com; it was re-written (mostly just re-styled) by myself upon their request.</p>
