An unofficial gpSP release has surfaced from an anonymous Chinese developer. It’s based off the work of Exophase and many others. You can find all the original documentation within.
I won’t bother attempting to translate the mess of a change log; however, I can tell you gpSP 03/11/08 works just fine under custom firmware 5.00 M33.
Now it’s time to exercise your Google skills and locate the Gameboy Advance BIOS image yourself; it’s exactly 16384 bytes large. Name the BIOS “gba_bios.bin” and copy it to the same directory as the gpSP EBOOT.
