this is wolfensteins engine with a custom in house renderer for gba. i optimized the raycaster until we hit 60fps then ported the state machines, mechanics and wolf 3d data over one at a time. the font looks bad because its scaled from the full dos framebuffer to the small gba screen. Also I am going to post the update where I adjusted fifa timing for audio. It was incorrect and crackling.

If you want to, I could rework the font to make it look better, I can do some sprite art, so modifying it to look better on the GBA screen could be something feasible on my end, both for Wolf3D and Spear of Destiny

Ah man.. I'm sorry, I'm too much of a dummy, to figure this all out. I'd love to play those too, this 'smoothdoom' thingy and this new Wolfenstein... but I don't know how.

When I extract them, I get:
- smoothdoom gba.xdelta
- wolfd3d gba better.xdelta

Would anyone be so kind, as to tell me, what exactly I have to do now with those 2, to get them to run on my GBA ?

I tried patching them my original rom files at this address: https://www.marcrobledo.com/RomPatcher.js/ but it always gives me an error message.

I recommend patching a clean "Wolfenstein 3D" GBA ROM using the Delta Patcher tool. The same goes for your ROM of "Doom."

The online ROM patcher last time I tried to use it didn't work.
 
Yes, I managed to do it :D Thx

It's so nice to have a good running Wolfenstein on the GBA. And also the refinements on Doom are really, really cool. It is still incredible to me, how this all runs so much better, than the retail releases ever could!
 
@capsulej actually yes, a lot in the case of DOOM 1, not so much with DOOM 2.

Doom1 is based on the Jaguar port of the old DOOM game but then adds in the missing stages. it is lacking some features, lacking some of the stages, has some changes to how much health, armor, etc pickups give. If you hit up gamefaqs.com and go to DOOM 1993 and grab the comparison guide here: https://gamefaqs.gamespot.com/pc/524287-doom-1993/faqs/1774

You can then on the guide ctrl+f (Find) 6. ATARI JAGUAR DOOM this section. That will tell you the pros, cons, changes, and stages list. THEN go and Ctrl+F again for 19. GAME VERSION COMPARISON TABLES That one is very easy to check because PC and JAG are put side by side first unlike the rest since many ports are based on it. You can also check the GBA table on that too since they're basically the same.

If you check those out you can see how different Doom on PC vs GBA is through the Jaguar section and GBA section.

Now as far as Doom II goes, it's lightly edited, another far more competent company did that one (Torus Games) and they straight ported it and did so up to the memory limits of the hardware. ONE stage was broken into 2 full stages because it couldn't fit in memory, also has green blood for a T vs M rating to be more sellable. DOOM2 GBA has a section for itself and also has its table with other D2 ports showing how close it is.

Because of that a few years back some hacks were done on both games, though really Doom 1 needed it badly, that bring the GBA experience nearly up to the quality of the PC fixing so much lost content, lost detail levels, etc. I loved then so much I paid for a couple translucent red shells, rewriteable boards with save and labels and have my own to have it on real hardware.

In regards to Doom 2, on the GBA, I think that the developer used another engine. I think it was the 'Ecks vs Sever'-Engine, which they also used in many other GBA First Person Shooters.

They basically used their own engine and rebuild all the Doom 2 maps in that engine. You can also kind of 'feel' it, being different from Doom 1 GBA. The shotgun has kind of a different impact pattern and textures blur, when farther away. Also, enemies go into an idle state, when too far away from the player.

That all didn't stop me from enjoying it, believe me, I played it a lot. But what always bothered me about Doom 2 GBA, was the awful input lag. I mean, you can kinda get used to it, a little bit, but still... it's bad.

But other than that, I still think it's an impressive port and it was jaw-dropping, back in the day. Hell, it still is, in my opinion.
