perfect paint? i think this is coded in amiblitz
It is. But it did use a few external tools (like a raytracer, I kid you not), some of which were available as WarpOS builds aswell (JPEG export, maybe? it's been too long).
and possibly a large portion of the PowerPC Mac library under iFusion, though iFusion
If your definition of "possibly" is "no %&$#?@!%&$#?@!%&$#?@!%&$#?@!ing way" - then yes, possibly.
iFusion never worked properly.
Not to mention running GL versions of the various Quake like engines at actual decent resolutions at good speeds.
With an extremely crappy mouse
You can already run Quake (or MAME...) on your PC - which has lots of horsepower, is connected to the best mouse, keyboard and monitor you have lying around and always has the latest releases available.
I was running PC ports on my classic PPC setup for years. It's not as much fun as it sounds, honest.
