Before I ask, let me say i'm not asking for this to be done, i know that you'd have to write a brand new emulator, I just want to know if it would be possible. Ok, now that thats out of the way, would it be possible to emulate a GBA link cable, by butchering a gba link cable to plug into the psp and a GBA. I know that on vba link, you can emulate the link cables, but I have no idea if it could work through usb though, but i cant see why a psp couldn't emulate a link cable. if you couldn't connect a gba, could you use local multiplier with psp for link emulation?
