I know. It will probably not work with all games but maybe with some.
I would also belive that keyboard handling would be a mess.

Well, but I was thinking on old ST games, not Falcon games. I guess ST games
are not that bad in this respect.

Talking about Atari emulators I just read a funny message in Why
not run SToNX under Mint+X? If it worked it would be totaly insane. Or you
could run SToNX under Linux on the Atari. There would atleast be no need
for CPU emulation. :-))))

This sounds realy cool and a funny project if someone wants to make a try.

We have been saying that for a LONG time now but still nothing has happened
and I realy doubt it ever will which is sad. :-\
