Trying to play/use GBA through Retropie
I have found several of what look to be the same file, gba_bios.bin that I have downloaded off of the internet. gpSP wants it named gba_bios.bin and it should be 16k in size. It is 16k in size in windows but when I use WinSCP to transfer the file over to the SD card it ends up as 0 bytes. I have tried Default, Text and Binary transfer types and it still ends up as 0 bytes. Any suggestions?
I transferred the exact same file last night with no issues, but I was using a mac and transferring via FTP. I know it’s extreme but have you tried putting the SD card into a card reader and directly connecting it to your PC for the transfer? I know it’s not ideal but should work.
If that fails, you’ve got an issue with the file I’d presume.
I was able to get the bios transferred by putting the card in a windows machine and copying the bios file to the boot (fat) partition. I then moved it via command line after it booted and now my GBA emulator works.
