What is GPBioS ? GPBioS is just a bios ( not a firmware ) which start directly your own OS if you want. It's THE answer to many bad Flash !!! If you choose GPBioS, it's maybe the first but it's surely the last time you flash your GP32.
What it is exactly ? It's a bios which run boot.bin or boot.fxe on the directory of your SMC Do you want to boot with wind-ups on a smc and boot with the original korean firmware on an other smc ? Don't need to reflash your gp32. It's possible and it's too simple with this GPBioS.
And ? And others things !!! Do you want to boot to your favourite game, application or emulator ? it's possible with GPBioS Rename your fxe to boot.fxe on your gp://gpmm/ directory and you'll boot to this application. If you want to stop to boot with this application, renamme it to the original name. (A or B when you start your gp32 to boot with the kr-en firmware)
