The controls for the PSX and N64 games would be udder madness to try and use on the tiny droid keyboard though. I would really like to see how the dev of one of these emulators would go about mapping the controls to where they are actually usable.
Map your own controls or buy some kind of gamepad accessory. Would probably also be on-screen controls as an option too. The controls don't matter, what matters is making the games play. For me I would probably only play simple games that only use a few buttons, those are the type of games I prefer to play on my phone anyway.
