Tomb Raider (1)

 Yesterday (21-01-2022) I did a quick port of OpenLara to the Atari Jaguar. I'm just using the 68000, the other processors DSP, GPU, and blitter are stopped, of course, I'm using the OP or you won't see anything. 

You can see a small video here. Yes is running at 1FPS or maybe less.

I'm sure that the GPU is fast enough to do all 3D transformations for this game and most first-generation PS1/Saturn games but there are some problems.

• The 68000 is too slow, is ok for a Genesis/Megadrive game, but it's too slow to make a modern shoot'em up (have a look at Sega Saturn games) with dozens of sprites, for a 3D game... forget it.
• The more you use the Jaguar's hardware the fewer bus cycles are left for the 68000.
• The Jaguar has only 2MB of RAM, the code takes 285Kb, and you have to store all textures, sounds, and 3D models. Just have a look at the filesize, almost none of them fit in RAM.
• I think that the game could look great in CrY mode but the blitter can't expand pixels, which means that you must store the textures in 16bits mode, and that will eat the whole RAM
