Open Source GTAIII

I found this today. It looks like it's been in the works for awhile in early stages, but is starting to gain attention now. It's called OpenRW. An open source GTA3 engine. Really cool stuff, I like seeing open source engine re-implementations

GitHub

Out of the many open source engine rewrites, I think that this can totally be ported to Dreamcast. Along with OpenMW (TES Morrowind) and Xash3D (GoldSRC / Half-Life). It'd take a crapton of work, but those would probably be the best possible games to port imo

Who knows, this could eventually work with Vice City and San Andreas. Since I think they all used the same engine, with minor engine improvements between each sequel

I could see 3 and VC to run on a dreamcast, however SA ran on an entirely revamped graphics and physics engine so I can't see myself play that any time soon. Now the only problem is how to get the music streaming to function properly.

Anymore on this ? The 3rd GTA was awesome as all hell AND I remember how that was in the NEWS all the time.

Here's a link to an unofficial build, haven't tried it yet but based on the github page I think it's a Mac only engine-

I wouldn't hold your breath on anyone getting OpenRW working on the Dreamcast any time soon. Just a quick look around the repository and the README for it shows that it requires much more modern GPU support than is even remotely possible on the Dreamcast. They specify that the code requires OpenGL 3.3 support (along with GLSL v3.30 to go along with it). The Dreamcast video hardware has no support for shaders (GLSL) at all, and the OpenGL-like implementations available only support up to roughly OpenGL 1.2.

Basically, if it was even possible to get it to work, the entire rendering portion of the code would have to be rewritten from scratch.

it was cool for you to weigh in. but i'm sure you know how it is when you see old semi-cringe posts you made a long time ago

we can dream 8-)

plus there would be obvious disc swapping involved between islands due to lack of space

I just wanted to make sure (after I noticed the thread from whoever bumped it) that the issues on the technical side were pointed out. ;-)

Thanks for the link.

this is a bit of an old thread, but i do think RE3 (the source code decompilation) was finally done, But i will admit i am not technical at ALL to even think of attempting this., but with it and simulant, i'd be surprised if it doesnt get a look-in to see what parts of GTAIII work on DC and what wouldn't work.
