This tool can be used to alter the boot logo on a GB300 handheld gaming console. 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! 🙂
Thank you to VonMillhausen for the original version of this tool, for the Data Frog SF2000: https://vonmillhausen.github.io/sf2000/tools/bootLogoChanger.htm
The boot logo resolution must be 640 x 136. NOTE: The GB300 is NOT compatible with SF2000 boot logo's!
bisrv.asdSelect the bisrv.asd file whose boot logo you want to modify. You should probably make a backup of the file first, just in case! You can find the bisrv.asd file in the bios folder on your microSD card.
