Tomb Raider: Chronicles (Decompile)

[Gh0stBlade]

Hey everyone! I've been working on decompiling the source code for Tomb Raider: Chronicles (PSX) over the past two years now. We're starting to see in-game graphics in the emulated PSXPC_N branch.

I thought some of you might be interested, feel free to come along and make contributions

Looks great! I actually stumbled upon your project a while ago when I was doing some decompiling myself and found it to be really interesting and useful. If there are any particular techniques/insights you've discovered in your research of the code I'd be really interested to hear them.

Bloody hell, that's going to be a mission to reverse. Why Tomb Raider though. Why not do something more popular like Gran Turismo or Crash Team Racing. It would be awesome to add in Link-Cable support to Crash Team Racing or Gran Turismo

I will definitely consider writing something up with hints, tips and techniques on decompiling PSX games at a later point. It's just tedious and time consuming work. After two years we finally have the title screen showing.

I chose Tomb Raider: Chronicles because I'm a fan of Tomb Raider. Also, we have debugging symbols for the PSX version of this game which makes reverse engineering much easier. There are other popular games which I wanted to decompile such as Legacy of Kain: Soul Reaver but unfortunately I cannot work on these other projects since it's already enough hassle with just one.

We actually wrote a PSX SDK HLE emulator to get the project running across PC, Linux and Mac. It is still a work in progress though and there are many features missing from the emulator and some bugs to fix.

Hi,

I'm glad you found my gte code useful, you didn't credit me but I know it so well that I can recognize it anyway

Where did you copy it from? It's been taken by a few people who claimed it as their own over the years.

Hi, thanks for letting me know. It's actually taken from PCSX-R emulator for now. In the future all GTE code will be stripped out (This is mostly used for experimental purposes on the PSXPC_N code path for TOMB5). I am more than happy to credit you for the work you did on that GTE emulator. Will update the readme credits section accordingly. (Note: GTE addition is relatively new to the project).

Cheers.

What are you going to replace it with?
