AmiQuake - new 68k Quake Port

[NovaCoder]

My new 68k port of Quake based on WinQuake

video

Requirements:

060 AGA/RTG (cyberGFX API)


I'm still paying with this port in my (limited) spare time and hope to get some more speed out of it.

I'm currently working on (yet) another 060 AGA port, more news when I get it up and running.  I might have something to show in time for the next Amiga meeting in Melbourne on the 6th of September.

I've already ported both ScummVM and BOOM to AGA.

Good work!!

Cheers, will give it a whirl. :pint:

Nice work, keep it up!
Wish I had a 060 setup just to try it.

WOW!  That looks amazingly smooth for a 68xxx processor.  I wish you only the best on finishing up.

By the by, will there be a network/multiplayer option?  I'm not holding my breath since I figure the hardware is getting taxed to the max as it is.

Is that AGA in your video?

No sorry, no network or multiplayer support will be added.  I find with my AGA ports it's best to only support the single player game mode.

Yes just good old double-buffered AGA, RTG would be slightly quicker.

Again here : seven emulated 060 instructions on this game !

Slow down because the 68060.library is not fast you know...

What about Cyberpatcher/Oxypatcher? I remember once playing Quake (on 060) and wondered how it crawled. I had accidentally disabled Oxypatcher. I think the speed drop was more than 50%.

Use the last version of OxyPatcher => v3.14

Cyberpatcher/Oxypatcher/Redox solve most of the slowdown but take some memory and introduce another potential failure point. They should not be necessary. Any compiler supporting the 68060 and compiled for the 68060 should not use trapped instructions that are not available in the 68060. Exceptions should be reported to the compiler maintainers.

That's the theory !

The reality is very different...

Yea, theory != reality or the world would be much different . Does the latest GCC generate trapped 68060 instructions when compiled for the 68060? The latest vbcc should not at least. It's targeted for embedded devices where there might not be enough memory for the 68060 software support library. The newest GCC versions seem to be targeted for bloated environments with high level languages where speed isn't important any more because it's going to be slow regardless :/.

AmiQuake is compiled using gcc version 3.45 and for 060 only, best version we've got I'm afraid
