Still on Morphzone ?
Yep, the main issue is that the keyboard is needed for the main menu... It would have to be patched too but I have no idea of the difficulty. During the game, it's perfectly playable though, you can even select the number of players with the pad only.
BTW, why would it need more than 2 MB ? Slam Tilt works on a stock A1200 and it doesn't need WHDLoad...
Anyway, I think the first issue can't be solved
