Best, wich means stable and fastest Quake port is ClickBoom's Quake 060. That was a separete update wich at least was freely downloadable from several web sites.
I was prety sure that it is Amigas Futuredownloads, but I could found it.
It is not Limited to 8bit screens, it supports every selectable screenmode.
Wazp3d is no go, it made possible to play some games with Amiga OS4 / PPC, but it would require too much raw CPU power and everything doesn't work.
