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, as well as alter the global mappings defined in the device's bisrv.asd 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! 🙂

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. If you're choosing your bisrv.asd file, you should probably make a backup of it first, just in case! You can find the bisrv.asd file in the bios folder on your device's microSD card.

Step 2: Choose your button mappings

Instructions for Step 2 will appear here when you have chosen a file in Step 1 above.

Step 3: Save your mapping changes

Instructions for Step 3 will appear here when you have chosen a file in Step 1 above.
