I thought by now we were discussing the "stick figure/simple 3D characters" idea? That obviously won't look anything like Virtua Fighter, but that's done and dusted at this point ;)

No problem, it's sometimes hard to tell in text communication ;)

That's an extremely pessimistic view. You're essentially saying that adding a character/background means the framerate goes down by factor of about 100. This is really unlikely to be true even if we...

Thanks, I like flat shaded 3D and that runs very nicely. It also is interesting to see this is an 030 demo because that does show very well what you can't expect on 030 (Virtua Fighter) and what you...

Better option in that case is probably to switch base colours a bunch of times during the screen. But at any rate you won't get a full 24 bit set then.

If you do, keep in mind that Dual Playfield bobs are either 3 or 4 bitplanes deep (OCS/AGA), not 6 or 8. I made that error once or twice and it made everything seem much less nice than it was :D
