The game logic runs on a different clock. Visuals get tweened between those frames sampling animations and shaders at the higher frame rate for display. I suppose it’s not a “full” decomp in that it doesn’t try to strictly emulate any hardware anymore. Also a lot of the game was a inhouse scripting language. So pulling that apart got me really far.

I decompiled all of the state systems for the story and gameplay mechanics. The rendering and drawing of the models is generic as I didn’t care to emulate the nuance of the ps2 architecture. I’m actually un-baking the shading from the scene and then relighting the scene dynamically.

It’s pretty far along. Given the nature of the game it’s difficult to say if all the pathways are done. But alot of it was an in-house scripting language. Right now I am overhauling the lighting with realtime shadows and weather n stuff
