Not as it currently stands. A clean room reimplementation could, of course, do anything.

There are some challenges even there, though. The wall texturing doesn't translate well to standard hardware texturing model. It uses large horizontal textures from which power of two wide vertical slices can be tiled out along wall spans. These slices can be pretty much any offset from the left edge of the texture and can be stretched or shrunk to fit a whole number of tiles in an arbitrary long wall segment. This isn't a great fit for the texture wrap modes in Warp3D/GL and would probably necessitate creating lots of smaller textures that are that specific width. You've also got the whole lightmapped sprites to deal with. Those can probably be converted into some form of bump map for R100/R200 but there's not much you can do for older boards there.

Another challenge is the sheer scale. The open expanses can be very large and translating to normalized depth for depth buffering may be problematic.

Thank you, that was a very informative answer. :)

If it's any consolation, it's on my personal Todo list to explore RGB rendering for RTG. The engine makes a lot of use of shading that could work quite well for 16 or 24 bit nodes.

The RTG engine works really well other than the energy/ammo displays not displaying text correctly! Got an extra 6fps using the RTG version on an 060 machine in full screen! Deathmatch over null modem worked great and is a pleasure to play!

You're going to need that extra FPS by the time my mod is finished.

Out of curiosity, what was that machines full specs? Also what was the peak FPS you noticed and what would you say the average FPS was hovering around?

I'm hoping to try it out on my towered A1200 soon

060/50 Picasso IV with 100+MB of Ram

It hovered around/averaged 16fps with some drops to 14fps. I'd probably drop to 3/4 size window for single player but it was fine for 2-player (no monsters).

Thats cool, thanks for that - am I correct in assuming you're running an A4000? Was this also in full screen or 2/3

I think when I tested a version from back in April (AGA only at that point) on my desktop 1200 with my TF1260 (50MHz) I was getting around 9.5 FPS in full screen, with about 18.5 FPS in 2/3 window (obviously this was a couple of versions ago - so I'm not sure what other speed increases it might have seen since)

Overclocked to about 84 I was seeing 13.5/27 FPS respectively.

If you're FPS was with the game in full screen, it make me very very curious what sort of FPS I would get on my Voodoo 3 3000 & TF1260 towered system.

I will have to get the system up and going ASAP!

@Amiboy

Yep, it was full screen. The PiStorm32 by equivalent is a solid 50fps now in RTG mode! They are both playable in deathmatch full screen with no noticeable advantage (at least at my skill level)!

Just downloaded the latest Karlos Mod files! I'm expecting great things as it's been months since I've seen what he's added!

...say goodbye to my 6fps speed up in fullscreen on a vanilla 060!!

HERE are the new executables including for the RTG engine! Karlos says you shouldn't try the latest mod assets with the latest engines! Waiting for confirmation as to why!

Confirmed working!!! Let's blast some modded breed in RTG!!

Chip Ram write speeds sill cease to be relevant for PiStorm users before long as there is already some RTG support. For the moment, the in game RTG is direct but the menu screens are still rendered into chip memory and copied. The menu code is pretty convoluted and needs replacing anyway.

Where the new RTG engine can be found? This link results into a 403 Forbidden.

Also, do we just extract the new engine to KarlosTKG/game and we launch?

The "Game" folder includes the full game plus the mod?

I downloaded "ab3d2_Andy" from EAB Zone and it loads/plays works on MorphOS after a brief test but I 'll return on it with more test.

Edit: ^ Scratch that, it froze a couple of seconds later but I think I am using the old RTG version.

The latest engine builds are attached in an lha archive to this post:

https://eab.abime.net/showpost.php?p=1619815&postcount=2675

You can put them in the Game directory of Karlos-tkg and edit the KarlosTKG script to run the executable called "hiresC" rather than the out of date build included in the mod.

Try it and see.

I try it.
It is much better than original version from 1996.
It is easier to setup.
Works without problems.

But it don't look like in 1996.
I know we use two or three times wider monitors.
And everything in 320 resolution fullscreen looks weird.
But after all it is not the same.

Maybe it should be ported to OpenGL. Even 1.x.

@Karlos

Also posted in the EAB thread;

System specs;
Towered A1200
3.1 ROMS
OS3.9 BB2
TF1260 @ 84MHz
(can clock slightly higher but this frequency is definitly 100% stable)
128MB Ram
Voodoo 3 3000 (Mediator)

Game settings;
HiResC
ScreenMode: Voodoo @ 320x240 @ 8Bit
2/3 play area screen size
Simplified lighting

Result;
FPS (on first level) of up to 40-50 in some areas (mainly the smaller tighter spaces), in the larger more open areas I was seeing around 23-24 FPS.

Question;
If you hit escape to bring up the main menu I didn't know how to exit the menu to get back into the session I was playing (I wanted to change some of the default key bindings during play).

Is this possible to allow user to get back to the session they are in (or have I completely missed something), or do you have to re-start from whatever level you were on?

Also, don't know if this is useful information or not but, as the game was running my Roadshow demo timed out and pushed my view back to Workbench. I was able to interact with WB without any issue and once I clicked OK on the time out pop-up it pushed me back into the game without any noticeable issues. (I know you are looking into an exit game option - but hopefully this shows that its almost good to go with that).

Anyway thanks for all the amazing hard work you are all doing! Please keep it up.

@ppcamiga1

If you want an OpenGL version I can only suggest a clean-room reimplementation. Effort has started on introducing C code to the engine, but I think you'll be waiting some time for a pure C version.

As our resident PPC fan, you might consider looking into something like http://aminet.net/package/dev/asm/PPC68k20 to port to PowerPC. I remember playing with this tool a long time ago but had no real need to use it, so I don't know how effective it is.
