I'm new to the boards, and new to hacking in general, but I was just wondering if it was possible to compile a bunch of different roms into one? And make a selection screen?
If you're talking about gba there are some programs that can launch roms, like pogoshell, it even creates kind of an operative system (it's more like a launching system...)
Not without a hell of a lot of work and some serious programming knowhow.
Right. It's going to be a good deal of work and definitely require some programming knowledge, even for games of the same system. pogoshell is an example of how you could potentially do it. You could create a simple BIOS or OS type program that acts as a ROM manager. I'm not entirely sure on the details as I've never sat down to think it out. I'd imagine difficulty will also depend on the platform in question.
All you really need is a hardware-assisted reprogrammable memory mapper, and a small BIOS program to setup your memory mapper. You'll obviously want to program the memory mapper using a routine that is executing in RAM. Then just perform a faux-reset (doesn't have to be perfect), jump to the cartridges' reset vector location and you're done.
Hmm... I think the only console that supports those multicart bootlegs is the NES. There's a couple out there too and they emulate properly on fceu (I think they emulate on fceuxdsp)
