DOOM on atari st

[havoc]

lots of misinformation on this thread... start understanding by reading this basic tutorial:

I know what a raycaster is, I have writen one myself on PC some years ago, but I don't think Substation or Destruction Imminent uses it (Ok maybe they use it to get data for the room so they don't need any 3d calculations, but not for the texturemapping). Wolfenstein on ST uses it, but it needs a c2p conversion to and you get 160x100 resolution if you want to have some frame rate. Substation and Destruction Imminent is 320x200 and faster than Wolf3d so they can't use texturemapping in the same way as wolf3d, so they must be doing it in ordinary bitmap mode and then you can't have a real texturemapper, so it must be some trick.

Hmm, does Substation work on an ST? For some odd reason I was thinking it was an
STe only game - prob wrong though. (or maybe it was enhanced for the STe?)...

[Zamuel_a]

I think Substation is for STE only. It has digital music in the menus anyway.

What version is this?

This looks like a real playable version with enemies. The best I found was doom081, but that one didn't had any moving enemies. From the look of the video it's very slow. Even slower than the versions I tested on Falcon and a 32MHz TT should do it better I think.

As the description says, it's Patrice Mandin's port.

Yea, I saw that now

I saw on his website that the sourcecode was there to. Then it would be possible to check it and maybe do some improvements (if it's possible). I don't have a GZ packer installed so couldn't check the files right away. Had been interesting to see if he used a c2p technic or only bitplane mode. From the speed on the TT video, it looks like it's all in bitplane mode.

[Zamuel_a]

I tested pm-doom on my TT and it was a more complete game than the other versions I tried, but so slow! It was maybe 1fps at best and it didn't matter if I used low or high detail or turned off floors/ceiling or even used the smallest window size. The speed was more or less the same, so there must be some fundamental error on the drawing code. Other than that, it looked ok:P

[Zamuel_a]

I got the source code and looked at it alittle and I can't find any "chunky2planar" routine in there and the drawing routine is complex with alots of rolls and stuff so without looking into exactly how it works I would say that it draws the bitplanes direct and that's why the speed is so low. Tobad since it's a rather complete game.

[lotek_style]

Substation definitely is an STE only game.

[MacFalcon]

Well I can´t believe that pmddom is such slow on TT... I definately had it running at playable speed and in a playable size on my 25 MHz Falcon with 14 MB RAM. This was version 0.32 of pmdoom, year must have been around 2003. (Btw, the first scummVM version also ran on this machine, around the same time, even with speech from cd... little slow but still a burner!)

If you look at "Running", I think Doom *might* be possible at playable speed on a plain falcon, but never ever on ST. Sure if you reprogram it in 16 colors or less (like the speccy or c64 version) you could get it running, but I think we already have better alternatives...

Yes I tested Destruction Imminent some time ago and it's a fast game

I was wondering if they're still selling it.
There's only a demo on PlanetEmu. :-\

Or this one http://www.youtube.com/watch?v=O5HDYNkt ... re=related for Falcon. Most interesting.

Yerz: send me a reminder. I think I should have a full version of D.I.

[RetroGamerUK]

I suspect to make a DOOM port for ST it would require to make entire engine "from the scratch". Just like they did DOOM on ZX Spectrum 128K. They had to resign from many features just to make the game possible on Spectrum.

Doom on the speccy? lol I have to see that!!!

[Mug UK]

Look for yerzmyey's videos on YouTube - he's a member on here too but he's also a Speccy fan (normal & the turbo-charged variants out there).

Wolfenstein on the Speccy: http://www.youtube.com/watch?v=n53-M6W2wEU

He includes a recording of a small test program to prove it's running on a 'normal' Speccy 128K at the start of both videos.

At least looking at DOOM, it will not make me get sea sick.
On the PC version, the fisrt time I played DOOM it lasted less than 10 mins & I felt sick.

Must download these for my Spectrum 128K +2a and run them through the Compact Flash Card at some point.

Guys, the D.I. 3D game works on my normal Atari STfm 1Mb!!!!!!!!!!!!!!!!!!!! =8-D
It's a great work!! (Also with fully digital music and fully digital fx)!!

I'm playing it at the moment, for a few hours, hahahaha!! Good one!!! I knew it had to be possible on regular ST!

[kristjanga]

bad mood has the fastest doom engine i have seen
you programers should check out that source code

[kristjanga]

perhabs it is possible to port the jaguar version over to the falcon

[kristjanga]

okay so i had nothing to do today so i made a video of my falcon playing some games and in the end you can see the bad mood engine hope some one can finish it into a playable game

1.Substation
2. Wolfenstein 3d
3.Moongame
4.Des Lasers & Des Hommes
5.Cannon Fodder 2
6.Bad Mood Doom engine

[yerzmyey]

That's interesting.

I didn't know that "Substation" works also on Falcon. Do You have any HDD version or must it work from diskette?



Ah, one more thing - "Des Lasers & Des Hommes" - I haven't seen this game before. Is it for ST or F030? I'd like to see that if it's anywhere on the Net. Any links maybe?



PS: Rammstein rulez.
