Classic Doom ports running on AmigaOS 4.1

[drHirudo]

Since the previous thread was placed in the socks drawer, I don't know if Iggy will see my answer, so here it is the answer to his request:

Hey doc,
Any chance you, Hotrod, or someone else could try the version Karlos used (DoomAttack the 040 optimised version) on a faster OS4.1 platform like a SAM or a Pegasos?
I'm curious to see how well this would scale on faster processors.

Well, I did not ran it on SAM or Pegasos, because I don't have such machine, but here it is running on microAmigaOne.

For comparison, I also ran ADoom (Another Doom port for Amiga - the 68K version) and then PrBoom. PrBoom is old compile with the static SDL that takes all the resources (the early one), so, as seen on the video, the 68K ports perform better than the crappy SDL port.
ADoomWOS is also in the drawer, but I didn't run it. It works with the GuruMeditation's WOS Emulator after ignoring a Grim Reaper warning.
Any comments or other requests are welcome.

Hi,

I watched your video through to the end and there was no difference in speed between any of them  lol

PrBoom feels the slowest for me, but it is static compile against one of the first SDL ports, which was taking all the CPU resources (using busy loops for timing or something). The later SDL did not have this feature, but the next PrBoom is using GL, so it is not relevant to the older classic ports.

[drHirudo]

Why not port something more advanced and flexible like Odamex, Zdoom, or at the very least PrBoom Plus?

PrBoomGL works very well on AmigaOS 4 - http://www.os4depot.net/index.php?function=showfile&file=game/fps/prboomgl.lha.
The clip was demonstration of how games compiled for classic Amiga run on AmigaOS 4 plus comparison with same game compiled for AmigaOS 4.
PrBoomGL uses 3D hardware acceleration - it is in different category.

[drHirudo]

I recorded the PRBoomGL on my Amiga machine. It looks much better than the classic ports, and the option to have soundtrack really adds to the atmosphere:

Btw are you sure it is WarpUp version? I once looked at it and despite what arch in readme states I recall it really is PowerUp version.

If the Guru Meditation's WarpUp emulator works for PowerUp executables, then I am not sure. It says WarpUp, but there is also PowerUp referrence in the executable.

Nice Vid and avatar, I dig those retro girls.

Fish is bringing PrBoom + to Aros and MorphOS has old PrBoom. MorphOS' port is only in software mode, but hopefully my money will talk and I can maybe pay someone to update it to PrBoom + with GL...

Considering that my Star Wars project will play nicer with free look.

I should be posting a video or two of my progress in time.

The GL port really renders better graphic to the old game. But it is still not full 3D like Quake for example. If you rotate around the dead bodies, their legs will always point to you, because it have limited images in the game (so not really 3D, but still raycasting).

I did not try the different wads, but the Batman mod I tried some years ago worked okay on the classic ports.

And yes, it's great being able to use mp3's with Doom isn't it?!

In my video it replays the original MIDI files of the game with the GUS and Timidity libraries. It uses less resources to play MIDI than MP3. When Doom was released for first time, MP3 was only starting and not yet popular. Most of the games at the time are using the crappy MIDI than sounds worse than Amiga MODs.

[drHirudo]

Its funny because playing Doom on my A1200 "feels wrong" because of the MIDI music.

Doom Attack have P61A plugin that can replay Amiga mods converted to the Player 6.1 - http://aminet.net/package/mus/misc/P6102.
But with fast macine, you can launch AmigaAMP and listen to any MP3s you want. They won't switch with the levels, but still better sound than the MIDI.

[drHirudo]

Ah... that is another ADoom build... I guess there are several then... :-)

Damn PowerUP vs WarpUP vs WarpOS vs MorphOS vs AmigaOS 68K vs AmigaOS 4 vs AROS vs E-UAE vs Amithlon things. They only bring confusion.

But seeing that the latest MacOS X does not support PPC code, then probably the most compatible OS with different versions of itself, that I have seen is Windows!

[drHirudo]

@XDelusion
As I see on your preview, the engine is still raycasting with OpenGL rendering. It will probably work on PRBoom, but not on DoomAttack on 68K Amigas. I remember many mods did not worked properly on classic Amiga Doom compilations because of the extra features needed.

Many years ago when I played Doom occasionaly on my Amiga 1200 I remember most of the Total Conversions were performing slower than the original Doom WADs and most of them did not work at all. There was Star Trek, Batman and other, but most of them where mostly graphics conversions, but not many new levels and maps. I love to play Total Conversions that give the feeling of entirely new game.
