It would probably require a lot of soldering and hardware to dump it off the chips.What tool should I use to dump the Game Boy BIOS and the Game Boy Color BIOS?
What do you mean?The latest version is included.
Well, I would guess that nobody made an easy-to-use tool to dump the BIOS.It would probably require a lot of soldering and hardware to dump it off the chips.
Something like version 1.0 of the tool.What do you mean?
It's basically impossible to write a tool for that. I doubt you could pull that off on an Everdrive with a homebrew tool.Well, I would guess that nobody made an easy-to-use tool to dump the BIOS.

There could be a homebrew tool like a Game Boy (Color) BIOS dumper that can dump a BIOS on an Everdrive flash card.It's basically impossible to write a tool for that. I doubt you could pull that off on an Everdrive with a homebrew tool.
I don't think that's technically possibleThere could be a homebrew tool like a Game Boy (Color) BIOS dumper that can dump a BIOS on an Everdrive flash card.
It's not externally accessible either, the only option is clock skipping/power glitching/rgh/whatever you want to call it to skip the instruction that disables the bootrom, THEN it can be dumped by homebrew (that sends it over the serial port, maybe it copies it to SRAM, etc)Judging from the Gameboy pandocs, the BIOS is stored on a ROM built into the gameboy itself which becomes inaccessible after any cartridge is launched. Therefore, it isn't possible to write a homebrew dumper. You'd have to work with soldering and probably glitching the microcontrollers to dump anything
Yeah I just read how it was actually accomplished. Impressive stuff tbhIt's not externally accessible either, the only option is clock skipping/power glitching/rgh/whatever you want to call it to skip the instruction that disables the bootrom, THEN it can be dumped by homebrew (that sends it over the serial port, maybe it copies it to SRAM, etc)
So to dump a Game Boy BIOS or a Game Boy Color BIOS, all I have to do is to insert a flash card like EverDrive, boot up a BIOS ROM, and maybe swap cartridges to get a BIOS dump?Yeah I just read how it was actually accomplished. Impressive stuff tbh
Wh... What? How did any of my or somebody else's posts lead you to that conclusion?So to dump a Game Boy BIOS or a Game Boy Color BIOS, all I have to do is to insert a flash card like EverDrive, boot up a BIOS ROM, and maybe swap cartridges to get a BIOS dump?
No, you have to get a flashcard (or bootleg, etc) with a dumper software, then do nasty hardware tricks at the right time (which can be figured out by... looking at an already dumped/disassembled bootrom to figure out instruction timings; the first time it was done by chance) to skip the instruction that disables the bootrom, then using said dumper software (which may or may not publicly exist) as neededSo to dump a Game Boy BIOS or a Game Boy Color BIOS, all I have to do is to insert a flash card like EverDrive, boot up a BIOS ROM, and maybe swap cartridges to get a BIOS dump?
