Data Frog SF2000 Button Mapping Tool

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 bisrv.asd BIOS file or in the KeyMapInfo.kmp 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.

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! 🙂

This tool was originally written by nikita.burnashev (email) gmail.com; it was re-written (mostly just re-styled) by myself upon their request.


Step 1: Select bisrv.asd or a game ROM

Select the bisrv.asd (for global device mappings) or game ROM file (for per-game mappings) whose button mappings you want to modify. You can find the bisrv.asd file in the bios folder on your device's microSD card.
