Hi, I'd like to build a custom GBA cartridge to attach some hardware, like a keyboard, to a DS. I'm looking for some pointer as how to access the GBA port from the DS. Has this kind of thing already been done? I need to know also what maximum current I can draw from the GBA port without risking to fry it. Is this information known? On a related note, what is the state of the dslinux project? Is it still active? Thanks.
