Sorry for this "looks-like-clueless" post, but I'm stuck in a thought: in GBA you are able to play GB games, right? The cartriges match in physics and system (Though GBA carts are far more advanced, of course). But when it comes to emulation, most of GBA emulators don't allow GB games to be played, either because of no compatibility or system differences. If a GBA emulator is to emulate every aspect of the console, why most of them just cannot run simple GB games in addition to the GBA ones? I think the only emulator capable of doing such is VisualBoyAdvance.

Ah, so there's a switch there to change between systems... hmm, that's more than clear now. As I don't have a GBA (I have glanced at it in my hands, but I didn't notice everthing about it physically), I couldn't tell. I just read it all the time that it actually runs GB and GBC games, so I thought.

That was my guess... I mean, this emu's system is not a single code for both consoles. Forgotten took separately the code for GBA and GB, and then put it together in only one emu, just like a multiple emu system. At least THIS guess was right (I think).
