Re: SCR File Format Documentation
Is this ever gonna come back? It will really help with reversing the game.

Re: OpenGTA2?
I think the first thing to be done is to collect all known versions of GTA2 for cross comparison and hope of any symbol leaks or debug compiled versions.
I know of these versions:
-PS1 release
-PC demo
-PC retail
-PC "rockstar classics"

Re: OpenGTA2?
Yep I fully expect this would be a multi person multi year project. Also agree that it can't really be automated. It would be manual work on around 5-6k functions.
I wouldn't do this alone if but we had say 5-10 people working on it then it could be possible to do within a few years.

Re: OpenGTA2?
I wonder if anyone would be interested in fully reversing GTA2 original exe? This would mean: 1. Disassemble the game to asm source. 2. Re-assemble and patch any time stamps in the PE header/debug info so it produces exactly the same original exe file. 3. Re-create the MSVC6 build environment. 4. Re...

Re: Just question of GTA2
I think the best way of doing this is just to create an open source engine. But to get it "true" to GTA2 you'd need to do a lot of reverse engineering to get the physics to behave in the same way. That is probably the hardest part .

Re: OpenGTA2?
That sounds like fixed point. I've fixed 1 and 2 now.
The float hacks in GTA2 is some variation of this: http://stackoverflow.com/questions/1349 ... -quake-iii all replaced with a call to sqrt() once I figured out what the hell was going on!

Re: OpenGTA2?
I think that probably requires also replacing some functions in the main exe - the game would still only be trying to render 4:3 amount of data. Stretching the viewport is easy enough though.Sektor wrote:Looking good, I hope you don't lose motivation. Will you add widescreen support?

Re: OpenGTA2?
3 bugs left...
1. Lighting is super confusing due to floating point hacks, see screen shot. Struggling to get this one working..
2. Main menu graphics colours are wrong - should be easy to fix.
3. The texture cache is always missed, probably doesn't really matter on modern hardware..

Is Epic GTA2 Map Editor on github? Perhaps he could try adding it there.

Re: OpenGTA2?
If I could get a copy of the IDB file that would be awesome :D! Edit: Got it now :) About 70% done in terms of having a working open source d3ddll.dll Edit: Some more funny screen shots of various hacks/progress. Edit: Almost have a replacement now, only lighting is missing. Colour conversion of on ...

Re: I'm creating new level designer, who will contribute?
Why not look into building into existing GTA2 map editors? Maybe have it work like factorio railway planner/tool.

Re: OpenGTA2?
I've started a project that reimplements dmavideo.dll and d3ddll.dll here https://github.com/paulsapps/GTA2Hax After this is done I will try to make OpenGL rendering engine for GTA2 and integrate ImGui for debugging purposes. Then I can start work on reversing car physics properly. It might even mak...

Re: OpenGTA2?
Has anyone worked on reversing the car physics? I've been thinking about perhaps using a dmavideo.dll proxy to try to reimplement the car physics functions. I think for a re-implementation the car physics need to feel very close to the original. All of the reading map formats/scripts etc seems like ...

Re: OpenGTA2?
Hmm I wonder why he would re-write it. Sounds like it was about 50% of the way there gameplay wise.
I've got a fork of the original code on github but I don't want to spend time updating it if its a dead end .

OpenGTA2?
Does anyone know what the status of this is?
Last news was this: http://gtamp.com/2009/07/18/gta2-news/
Now his site seems to have gone including the svn, but there is some mirror on github here:
