ZDooM

Has anyone ever heard of ZDooM? Would it be possible to port it to dc?

Yes, I've heard of it. I think it uses far too much memory for it to work on the Dreamcast.

By the way, what are the specs on a DC anyway?

Always impressive to see... This thing has power

actually, the dreamcast is more than powerful enough to run Zdoom

What is zDoom?
I thought it was only a engine win32 friendly. What are the advantages in it?

...Besides, wouldn't hi-resolution geometry processing look kind of...I dunno, bad when mixed with low-res textures and sprites? I have zDoom, but I only play the version that uses 3D models to replace the sprites...because the other looks really bad and mismatched. And I don't think DC could really handle the full-poly mode too well.

The Dreamcast is a virtual powerhouse. It may not seem like much, but think about it. Dreamcast can handle a maximum of 3,000,000 texture mapped polygons onscreen @ once, and about 5,000,000 if they are plain polygons without textures.

Character models running on the Unreal 3 Engine on low resolution are about 5,000+ texture/normal mapped polygons. If a Dreamcast game were to utilize 10,000 texture/normal mapped polygons per character/enemy model, you could have 100 onscreen enemies all @ 10,000 mapped polys each and only draw 1,000,000 polys out of the Dreamcast. The rest could be used for level design and whatnot. There might be issues with CPU clockspeed, but there are always ways to work around that.

The only REAL thing keeping this from EVER happening is the Dreamcast's total and utter lack of sufficient RAM. With about 16 megs of normal RAM, 8 megs of video RAM, and 2 megs of sound RAM, that leaves you VERY little to work with. If the Dreamcast had had 32 megabytes instead of 16, 60% of most games PC games up til now could be effectively ported, with little to no loss of translation. But, alas, the unsolveable RAM issue will keep that dream from ever materializing.

Actually, that's per second, not per frame. It's more like 50,000 polygons per frame at 60 frames per second, and that's assuming that you're using virtually all of the CPU time to generate polygon data. The PVR chip itself could easily handle more opaque polygons than that, but tends to slow down a lot if you start using lots of blended polygons.

ZDOOM would be nice...

...we just got Legacy (in alpha) on the XBOX!

Also with ZDOOM, you now get Strife support as well. A recent addition to the ZDOOM legacy.

They actually managed to pull that off? Nice.

ZDOOM Kicks serious ass!

XDelusion · Post by **XDelusion** » Sat Jan 15, 2005 12:53 am

Yep, supports:

DOOM
Ultimate DOOM
DOOM II
DOOM Plutonia
DOOM Evolution
Heretic
Hexen
Strife

Think that covers them all. Its a pretty nice package, it runs in software mode, and actually looks VERY good despite that! There is devinatly enough MOD-ability to it to make any DEVer adicted in an instant. But alas, I'm a Legacy guy, so no projects planned form me, though I do admire the ability to use sloped floors in it...

...not to meintion the Monster Resource WAD.

It's AMAZING!!!!!

Anyone tried edge?

When looking at that, i just realized that my laptop is lighter than my DC

hmm..
sure its allready been discussed very often but, has no one got ever a rammod for dc working? solder a second chip into it...
this is on the gp32 "really" easy... and on the xbox its also possible.. ok both use common PC Ram, but cant you just take the ram out of a broken Dreamcast if you cant find it?
this would be really awesome for homebrew..
ok i think you would have to make a custom bios, so that software can use the ram, but that shouldnt be to hard, right?

search the forums to see the hundreds of topics where this has been discussed.

if it shouldnt be that hard, then do it.

you can hook RAM into a GP32?

Any links or info on this?
