could somebody compile a win32 version fo this emulator

**blueshogun96** · August 31st, 2008

Afaik, it's against the rules to do that and start distributing it accross the forums. You'll have to compile it yourself. You can download a copy of Visual C++ express (at least I'm sure you still can), and then compiling is easy.

@Chrono, thank you sir. That was awfully nice of you to do that for me

I started working on some fixes for the NTSC version of BattleStar Galactica. It shows the intro and loading screens, but a memory related problem causes it to crash.

Somebody already tested Halo? would be glad to see any progress there

I remember running an emu that could at least show the titlescreen..

Futurama is built with an off-the-shelf engine called Gamebryo from Emergent. I'll look for other Gamebryo titles in the used-bin as we may have some luck with them as well.

No problem. One of the things that caught my eye from Hard core Rikki's post was the quote "The hex values of some D3DFMTs can change from one SDK to the next". This sure would explain some issues I've run into. Do you have some specific examples of enumerations that have changed across SDK versions?

It's another 5233 game, I used it to cross-check OOVPA's from Futurama. It's possible to get in-game, but it's very unstable and full of glitches.

For Cxbx code I use the integrated Visual Studio debugger. To debug game code I export the XBE to EXE with Cxbx and use OllyDbg. To explore and annotate game code there's IDA Pro.

Neat.

In it's current state Cxbx is not of much use to others than programmers who just want to play with the source code anyway. You can compile my branch with Visual C++ 2008 Express, MS Platform SDK and DirectX SDK which is freely available (well, at least in a monetary sense) from Microsoft if you have a Windows license. Cxbx still uses the now deprecated D3D8, the August 2007 version of DirectX was the last SDK to include it.

I'd like to upgrade to D3D9, some things would be easier to emulate, but others would require new workarounds. Most of all I's like to see backend plug-ins to get rid of the proprietary dependencies, but that's hardly realistic with the current project activity. Interestingly some of the Xbox D3D extensions are available in OpenGL. I guess they were added because Nvidia's chip already conformed to OpenGL.

At the moment I'm adding more primitives to the vertex buffer patcher and trying to come up with a sane way to patch vertex shaders that outputs direct screen space coordinates. As for Futurama the biggest remaining problem is all the black surfaces. It appears to be a lighting issue, because adding additional light by blowing up a nearby barrels will light up broken surfaces and show the textures. Well.

Alright then, I'll look for Gamebryo titles myself when I get a chance to buy more games.

Well, when I looked at the differences in the XDK header files, I noticed that some of the actual hex values from 4361 were different from 4627 and many others. This is easy to fix, but I've just been too lazy lately. I first found this out when I was trying to add support for Hunter: The reckoning. The funny thing about this game is that it enumerates every D3DFMT on the XDK even though Xbox already supports them all.

I have Celebrity Death Match, but I haven't gotten around to downloading your branch until today. Do you have a 5233 XDK? Or do you just force it to use another version (i.e. 5558)? If you need more XDKs, ask me. I have 5 versions, 4361, 4627, 5344, 5558, and 5849. Let me know if you have a 3911 XDK. People beg for DOA3 and other team ninja games alot

In the past I've had problems with JIT on my desktop. I recently got a new notebook and I'll try to make sure JIT works on it at least. I'll download OllyDbg. I read about it in a book about Reverse engineering. I beleive it was called The Secrets of Reverse Engineering. It helped me alot when learning about how Xbox works on the software level.

True, but it gets harder if this is the case for XDKs that never leaked, we can't create test cases for them. And if they changed D3DFMT constants, what else did they change?

I'm just speculating, but I'd guess they used a cross-platorm game engine that adjusts to available formats at run-time.

I don't have any exotic XDKs. When adding 5233 I manually compared functions to those found by Cxbx in 4627 and 5558 games. I didn't know 5344 was out in the wild, signatures from that XDK would probably have saved me a lot of time.

I have one 3911 game, 4x4 Evo 2. Not an exclusive Xbox title, but I'd like to look deeper into it anyway.

I'm not sure what else might have changed. I was also too lazy to look for other changes.

Yeah, I'd say so myself.

Martin_sw told me that 5344 and 5558 have many similarities in them. Usually the Direct3D stuff doesn't change much (afaik), but the DirectSound stuff varies alot. XDK 4721 is a good example. Games like Quantum Redshift and Shenmue II use it, but it's the sound APIs that stop it from working. It's mainly DirectSound and CMcpx APIs that are stopping from getting Robotech: Battlecry (XDK 4928) from working. All of the Direct3D initialization works ok and none of the shader parsers crash either. Anyway, I downloaded your branch yesterday and I was going to try some other 5233 games I had laying around (StarWars: Clone wars, Brute Force, and a few others).

I'll eventually get that game one of these days. The main reason I want a 3911 is because some really unique situations have come up in Azurik: Rize of Perathia. Besides the missing render states, it has a memory corruption problem and tries to create a blank shader with no code in it (after Cxbx parses it), no other games have these problems. I'm guessing that this is one of the hardest Xbox games to emulate of all time. Microsoft has been at it for years on Xbox360 and still can't emulate it.

Thanks for your work, i hope you keep it going. I have some questions:
Are you using OpenXDK or Microsoft XDK?
How do you know which XDK version a game is using?
I have Burnout 3 and i'll try to work on it (if i can), tell me the techniques you use and where do i get started.

Retail games are required to use Microsoft's official XDK, so that's what Cxbx is targeting.

XBE files contains a list of linked libraries and versions. Use Edit -> Dump Xbe Info in Cxbx to list XBE details.

This specific game is built with Link-Time Code Generation, meaning that we can't identify XTL functions with our current techniques. We'll have to make function signatures and wrappers for each LTCG game rather than for an entire XDK build version.

To get started contributing to Cxbx I guess it's the same procedure as with any other software project; get familiar with the code base and hack away.

If you are asking for the Official XDK it seems like you need to read the rules NGEmu/EmuForums Rules of Conduct

Well, they're a dev team with official MS licence of course

btw: does someone know weather that XDK thing is realy leaked? ( I don't want to know where to get it!

)

Game executables already includes the XDK blobs that needs reversing.
