Data Frog SF2000 Boot Logo Changer

This tool can be used to alter the boot logo on an SF2000 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! 🙂


Step 1: Select Original bisrv.asd

Select 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.


Step 2: Select New Logo Image File

Select the image file you want to use as the new boot logo. It must be 256 pixels wide and 100 pixels tall. Only PNG and JPEG image types are supported. For PNG files, transparency is ignored; also, you might want to make sure your PNG image has any embedded gamma or colour profile information removed first using a metadata scrubbing tool, otherwise the colour output from this tool might be incorrect. The image is displayed centred on a black background, so you may want to factor that into your design as well.


Step 3: Download Updated bisrv.asd

Click the download button for the updated bisrv.asd file; use it to replace the one in the bios folder on your SF2000's microSD card.
