Yes, I normally use WinUAE to run them, I imagine they would be too slow otherwise...

bitplanes no, but originally MAME was designed for 256 colour modes. It's only relatively recently that everything is done in true colour.

Not the 060 side of the accelerator, but I remember being able to run everything up to maybe Atari System I (Marble Madness, etc) on the Blizzard PPC/240. I would have to reduce fullscreen colors to 32 or 64 to get it playable though. Tried the 060 version, but was unable to get anything but pacman and the like to run at speed.

I got my A4000 working.

I just tried Ghouls'n'Ghosts on my CS-PPC. It was quite interesting...

OS3.9 AGA: 31% speed
OS3.9 Voodoo III (Prometheus): 30% speed (this should not be slower!)
OS4.0 Voodoo III (Prometheus): 35% speed!

First off, there's no way AGA should be faster, even if only 1%. Something's a bit squiffy there.
To back up the "something squiffy" theory, it's crazy that it's faster in OS4. The 68K emulation is very good, even in OS 4.0, but 18% faster than a 68060?!

My CSPPC is a 604e@200,68060@50, by the way.

Well, if Petunia on a 604@200MHz is only 18% faster than a 060, it's rather disappointing, actually

I bet the Prometheus isn`t doing DMA - there`s a thread or two about it somewhere. Something about a firmware update.

[zipper]

It never did without update.

[spirantho]

DMA is something different, it doesn't affect the speed of software like this.

As for it being 18% faster, that's really quite surprising. I know on the face of it it may seem like Petunia should be much faster, but remember the 604e is only 4x the clock speed of the 68060, which is also equipped with some quite fancy speed-up things like caches and stuff. Also remember that the 604e may run at 200MHz but the memory bus definitely doesn't, and in fact the 604e spends quite a bit of time throttled by the lack of L2 cache.

Either way, I'd say it shows that Petunia really is a pretty fine CPU emulation.
