I’ve just started a Gameboy development and music file archive with the aim to find and mirror Gameboy-related utilities for music and software development. Currently, the only useful section is the music tools folder, but I’m planning to expand the development tools folder as well. If you have any file that you would like to see added, or just want to comment on the idea, feel free to leave a comment here, mail me on the address given below, or join the discussion on chipmusic.org.

Thanks to Scott Evans for making Indices and thus providing useful information.

It’s also possible to edit the Game Boy Development wiki again. To get access to editing the wiki you first need to register a forum account. When you have activated your forum account, use the same username and password to log in to the wiki. We apologize for the extra step in the registration process, but we’d like to keep the wiki completely spam free.
The purpose of the wiki is to collect, archive and preserve information, documents and tutorials related to Game Boy development, as such resources are slowly vanishing from the internet. Tutorials, example code, obscure tech documents that you have lying around, anything is welcome.

Cherryroms

I’m not writing this post just out of personal nostalgia though. It was also on Cherryroms that neviksti first posted about his efforts to decapsulate a Game Boy CPU an extract the DMG-01 256 byte internal bootstrap which is used to check the Nintendo logo and checksum on a cartridge before deciding to allow booting the cartridge. The function of the bootstrap was known and even documented in a patent however the actual memory content had never been dumped up to that point, so neviksti’s effort brought something new to the table.

The original thread can now be read in its entity again on Cherryroms here or archived here.
