>has anyone got a list of games that will play from workbench on the voodoo / mediator setup?
So really you're asking for a list of games with retragetable graphics.
Although having said that, not all of them work in my experience, and its worth having something like NewMode or Modepro (Aminet) to help out.
The other thing is you could do what I do and have a TV card fitted to your Mediator and then feed your Composite out from the back of your 1200 into the TV card and then you can run pretty much any Amiga game in a window or full screen. Its not quite as good as RGB but I found with a decent quality (and short) lead the image quality is fine.
But back to RTG games....
Big Red Adventure
Black Crypt
Centurion
Civilization
Colonization
Crossfire 2
Descent
Doom
Doom 2
Duke Nukem
Dune 2
Exodus
Eye of the Beholder
Eye of the Beholder 2
Foundation
Freespace
Genetic Species
Gloom
Gunship 2000
Heretic 2
Lords of the Realm
Malice (Quake)
Napalm
PGA Golf
Shadow of the Third Moon
Starlord (!!)
Subwar 2050
Trapped
Trapped 2
UFO Enemy Unknown
Payback
Quake
Quake World
Quake 2
Some of these I just could not get to work in RTG, Trapped 2. Subwar, Starlord, UFO and others. Its a list I picked up from somewhere and may not be that accurate, I think some are just mode promotable but I'm not that clear on the issues.
You could also consider getting a Mac emulator and running some of those old Mac games.
Hope that helps a bit.
