Sabaho:
The OpenGL version of UltraHLE is in its last few weeks of development. It'll be released soon. I was lucky to have a 3dfx card and try it on my friend's K6-2 450 MHz, 128 MB RAM computer. We tried the 12 ROMs, most of them the standard ones you should try out: Mario64, Mariokart, Bomberman, NHL 98, Mace: The Dark Age (a kickass medieval character fighting game), Goldeneye, etc.
When I mean correct graphics, they were identical to the ones displayed on the N64, because I had most of those games, but with MUCH smoother and MUCH clearer display, of course because it was on a computer. Even on my slowass 233 MHz, 32 MB RAM slowmachine, they ran at 1 mile per hour, but with crisp, correct graphics and coloring. The textures were great.
If you want to try out your luck on a Glide Wrapper, visit www.ultrahle.com (if you don't have a 3dfx card a wrapper is necessary). If not, wait until the OpenGL core UltraHLE is out. It'll blow away Nemu64 completely. Sorry for the aggresiveness, but N64 gets ratted on way too much, especially by friends that like PSX more than myself, so they've pissed me off too much. Hope that helps out,
