Quake 2 ported to AGA

[Juz400]

Do any of the new instructions that `080` have help with the `matrix` calculations needed with 3D or are they more geared towards video playback?
Ive been watching alot of onelonecoder utubes, lots of C tutorials inc 3D

Crikey theres ALOT of maths to the 3D rotation, line of sight and then render to a 2D screen!
My ASM coding skills back in the day didnt include vectors, BOBs was about it unfortunatly...

Here is a video of me running this on uae4arm on a raspberry pi 4, 2gb edition.

Very cool, looks super-smooth. Wonder how fast a native port would be

Actually I think a pure Yamagi OpenGL port would be preferable, I'll try knock up a port this weekend

I'm loving my Pi setup with SC-55 support for games

Careful if you want it to run on an RPI4, you can't use the old legacy way, and need to embrace X11.
Isn't hard, just annoying. Had to fix my work program to support both methods.

Yes and no. The 080 has additional registers which the FPU can use. The higher number of registers is useful for matrix operations for which the only eight registers of the original FPU aren't enough to keep all the operands. Using these new registers in FPU instructions requires using new instruction encodings, hence, will be new instructions on the machine level even if the mnemonics for the instructions remain the same. Another important change in the 080 FPU is that it is fully pipelined. This means that a new instruction can be started in every cycle which means a massive improvement of MFLOPS achievable. There is work being done on GCC to achieve netter FPU code generation for the 080.

what do i need to configure in order to get cd audio working?

and what files do i need to copy for working addons? they are not in baseq2 folder on pc version, where all addons are installed. because i already copied all .pak files from baseq2 folder but there are no addons on amiga side...

so "supporting mission packs" is a fake i assume...

I don't even have an Amiga these days so can't really help you to get it working

I wish Nova would have another crack at this and add the ability to shrink the screen size back in

@Nova - here’s hoping you’ve had chance to have another look at this some Q2 optimisation and screen resize would be great

Have you tried the optimised version by Cosmos?

http://cosmosamiga.free.fr/download/AmiQuake2_115.lha

RTG version:

http://cosmos-amiga.fr/cosmosamiga/d...e2_115_RTG.lha

Lots of other stuff there, like Quake, Wazp3D e.t.c.

[trixster]

Interesting, thanks for the link. I’ll give 115 a try

[trixster]

Doesn’t appear to be much different - still 8.3fps timedemo demo1.dm2

Is there no interest in this version of Quake II? It's very fast in RTG mode, v1.34. Highest RTG mode listed is 800x500. It's really terrific!

There are 173 posts in this thread. No interest?

The most recent are mostly from 2019.

I suppose it's possible the reason for that is that it runs with fewer issues on more configurations than AmiQuake (I). If so, disregard.

It actually supports a max resolution of 1280x720 same as my ports of AmiDuke, ODAMEX, Descent and AmiQuake


You just have to make sure you have a 1280x720 8bit mode available to the games.

We're back up to speed. I don't think I could recreate that if I tried but I have all resolutions supported by Picasso now, same as the others. Weird. I went back in to play a saved game and the resolutions were there.

Excellent port as always, NovaCoder!

What hardware config are you playing the Q2 port on?

[Rotareneg]

I'm confused, why would anyone want to play Quake 2 on ANY platform?

FS-UAE OS3.9 w/ AfA. P96, A4000/68040-NOMMU. 256MB chip/other. I found that I had to take the resolution down to 672 x 540 (as opposed to the 800 x 600 I get in AmiQuake I) to take care of audio lag and some freezing of frames at higher resolution.
