Hehe cool...
Spooky as I recently tried ADoom for the first time on my 030!
Works fine, if a little jerky, but pressing F5 to go to low detail mode improves things.
I still haven't got quake working, either ClickBoom quake or Quake68k.lha from AmiNet, I don't think > 2 FPS w/ Quake on an 030 is possible really, so i'll leave that for my other machines.
(FYI the best port of Quake I have played is the OSX port, works great + looks great in all resolutions!)
