I've made a quick port of Doom to the PS2:

Maybe someone browsing these forums will make it more complete ? :-)

SDL-Doom 1.10 is one of the original Doom ports. Most of the existing ports have worked their way beyond Doom to the point that many only share a name and the wad file with the original game. I like to call original ports like SDL-Doom "Classic" Doom ports, while most of the new ones would be "Extended" Doom ports. It's easier to port Classic Doom as the Extended ports are invariably heavy on PC features. My own Doom port for the PSP was of the Classic variety.

I suppose I could work on PS2 Doom a bit.

Cool !
I must try it!

I'll look at the code for the sound issue. But not for now, I have other things I would like to do on PS2 (trying to port some PSP stuff to the PS2)

J.F. : be our guest ;)

[cosmito]

The port plays very well!
One of the things I would add would be strafing with the right analog stick.

The run mode would be nice, although joypad buttons are running out.

And weapon cycling is also a must.
I guess I must put my hands on the source soon.

Good work Lukasz.

[Lukasz]

Ptek: Adding extra bindings for the joypad buttons is easy, just add them in i_video.c / void I_GetEvent(SDL_Event *Event)

J.F: Your features for the PSP port sound great, keep us posted if you update the PS2 port ;-)

I've done some modifications to the Lucasz port.

Now it loads (only) from an USB mass storage connected to the PS2 and I also changed some screen settings. So it uses a non interlaced screen and I also stretched the image to meed the original PC version aspect ratio.

Get it from here
http://ps2homebrewing.wordpress.com/2008/02/19/modified-ps2-port-of-doom/

There you will find two versions : One that don't change the aspect ratio and another that stretches vertically to fill the screen - I find it more close to the original PC version.

Currently only binaries are available but soon (hopefully next weekend I'll post the modificed sources - I had to change the gsKit and sdl for getting the non interlaced screen mode).

I didn't touched sound nor controller settings yet.

If I remember rightly, the sound code in sdldoom is quite hacky. I'm not surprised it doesn't work. I think the guy was trying to make it so that sdl_mixer would not be a requirement or something like that.

I also tried to play a network game between a PC and a Mac using sdldoom once and it failed due to endian issues. If you want my advice, pursue PrBoom instead.

And sorry to break it to you but you're not the first person to run sdldoom on the PS2. That's the version I tried when I first got the framebuffer driver working with Linux 2.4. Still, the fact that you got it going without Linux is much cooler. Well done. (-;

I've updated my website with a link to this thread, nice work ptek :-)

Hmm nice!

Hi!

First, congratulations for this Doom port for PS2. I've tested on my 39001 console (wich have a 200GB hdd) and it works! I boot the game from uLaunchelf and it's very nice, but the loading screen takes a while.

I have some suggestions for this excellent port. The "Quit Game" option in main menu could be a link for an ELF (in this case, launchelf.elf on the hdd or mc) so when you quit the game, you are really doing it! hehe

Also, I couldn't make it works with others WAD files. I tried Ultimate Doom, and Doon II unsuccessfully.

I'm available to be a "beta tester" for the product. ;-)

[cosmito]

A very small update - enabled keyboard support. As simple as enabling it on SDL and do a rebuild :)

Get it here the binary :

@ dirsors,

I played sucessfully doom2 and doom ultimate... If you tried to run my modified version that loads from the USB keep in mind the WADs are expected to be at the root of the USB device.

I got the sound working in the lsdldoom port I did about a year ago. I pretty much just rewrote all the sound code to use SDL_Mixer and resampled the sounds to work with the PS2 implementation -- most of it's in l_sound_sdl.c. I think towards the end I kind of went nuts and tried getting music to work too, first using a hacked up version SDL_Mixer I added midi support to, and then by reading wads with mod music embedded. I don't think either of them really panned out.

Here's the last version of the sources I could find. I don't know if it compiles, but feel free to take a look at anything that could help out.

[Lukasz]

I just tried your port FeedBucket, it compiles just fine and sound effects do in fact work, however music doesn't (as you mention).

I compiled your port with romfs support and included the DOOM shareware data, which should run from both host, cdrom, etc.

Download here: http://lukasz.dk/files/lsdldoom-ps2-bin.zip

Included is DOOM.ELF and DOOMP.ELF (DOOM.ELF packed with ps2-packer)

I think further work should be done on this work instead of my hackish one, as it seems more complete ;-)

As a note, I sometimes got an exception when running the DOOM.ELF using PS2Link without romfs support.

Thank you FeedBucket and Lukasz!

Although the J.F. suggestion to go for a full PrBoom port is the best thing to do (more compatible with the custom wads outhere) this will keep us busy with something to play in the meanwhile - with sound :)

Very cool

[cosmito]

Time for some improvements on the lsdldoom : read on

I was thinking in creating a SVN repository to host the source for the lsdldoom so any interested could both checkout and commit its contributions.

I already know and used assembla.com for free SVN hosting and I heard of Google Code although didn't use the latter yet. Does anyone have other suggestions? What would be the best for hosting and allowing others to commit ?

I Tested the Lsdldoom port, it function great, and with sound, but my problem is the WADs, i put the wad and the DOOM.elf on the root of my pendrive, but the DOOM just don't use that wad,

what i'm dooing wrong??

thanks

EDIT:

I just Downloaded lsdldoom-ps2_v001.rar and it does not start

So what can i do?

thanks for the great work both Lukasz and ptek

and keep making ports please

[cosmito]

[diegox758]

I was using the lsdldoom that doesn't come with any built in wad, but the problem, is with the wad, the program just recognize "Oficial Wads" not the customs made by fans.

I'm happy playing Doom and having a lot problem at level 18 LoL

and again thank all of you for this Great Work
