Wolf4Amiga and Spear4Amiga released

[BSzili]

I know what you are thinking, why make another Wolfenstein 3D port, when we already have so many of them? While these all have their strengths, they have one thing in common: the recommended CPU to play them is 68040+. Since the original game only needed a 286, I though there must be a way to get it to work on an 68020 at a playable speed. In the end managed to succeed with some compromises. The game uses a 2x1 resolution, but it runs on an A1200 with a 68020 at 14 MHz and some Fast RAM, no CPU accelerator required! For more details check out the development thread:

Thanks BSzili

@Bzili : could you do the same treatment to Doom I & II, and also Heretic ?

The result in 2x1 is excellent, could those games benefit of it as well ?

There are excellent Doom ports for a Amiga, which are almost playable with 68030 50mhz with Low detail mode which is 2 x 1.

Better idea would be use degrared WAD file, like Atari Jaguar's like in this video [ Show youtube player ] CDTV with 68020 accelerator.

Congrats dude, you've done some great work in recent years

Thanks everyone!

It's not that simple, as there was a bit more to improving the performance than halving the horizontal resolution. Doom is a much more complex game with different bottlenecks. Even Blake Stone is far from being playable at 14 MHz, and that game uses the same engine.

Thank you for your efforts, @BSzili, your work is fantastic!

[CaptainPlanet]

Wow, this is amazing. I still had my Amiga when this game was big on PCs. Imagine if this had been available at the time? I would've loved to have showed it off to pee-see owners at the time!

My Amiga can do adlib too!

This is my thoughts also It's a weird feeling for me to play this today on my A1200. It was about 30 years ago that I last gave the game a go on my friend's then spanking new 486. Excellent work. Thank you very much BSzili!

Adlib is converted to an amiga format isn't it?

You see the music conversion when you patch the game

Or am I wrong?

[BSzili]

Thanks everyone. Technically it can "do adlib" via software synth, just not in real time. The converter program plays them back one by one and saves them as samples.

[gimbal]

That almost sounds like voodoo magic.

Wolfenstein 3D on MC68020? Finally! Thank you! 2x1 is hardly noticeable, if you hadn't mentioned it, I wouldn't have even noticed.

[ScottC2010]

Works really well on m KS3.2.1 with 8MB.
Though is there a way to change screen as a lot of blank space below it and maybe change from 2x1 to 2x2 or 1x2?

[BSzili]

I thought about this, but due to how the rendering works there wouldn't much benefit to a 1x2 mode in terms of speed. Also the 3D view will always have less pixels vertically, so I feel like 2x2 would reduce the quality of the graphics too much. This would be exacerbated by the increased field of view unless you want to simply chop off the sides of the taller view.
The more I think about it the more potential problems I see, so it's probably the best to leave this as it is. The 2x1 view is already a bit of a hack, but it benefited the performance at multiple levels so it was a worthwhile trade-off.

Not sure if you mentioned the extra levels for SoD from the PC GoG version work as well

I am having this issue shown in attached photo when running the game on my Amiga 4000 with a Cybervision64 and the lastest p96 on AmigaOS 3.2.1

It is using a p96 320x200x8 screenmode.

The right side of the display is flickering. When I lower ingame screen size the part on the right will turn black.

I will work when I deactivate this 320x200x8 screenmode in p96 prefs and will then run in an AGA mode without this issue.

I never actually tried any of the Nocturnal Missions, so it's nice to see them running!

Oops, it looks like I broke the RTG modes when lowered the 3D resolution to 2x1. I didn't think people would try it on a high-end machine, so I forgot to test this. I'll fix the RTG support in the next version.

Thanks so much for your work on this, BSzili. I am finding myself making time and excuses to play this game (which I have never played on any platform until now) on my Amiga and will be playing it through to completion.

Love it!
