5517 client source reconstruction

[0xpanadol]

I've been working for this for almost 3 weeks, completed most of the dlls and some major exe functions, ignored the network completly for now (I'll rebuild the whole network for both client and server in my own logic later)

I'm curious how did you reverse the dlls ? are you using IDA?

It should not reverse, but directly use the previously released C3SDK.

Of course, this is my guess.

I think there should be a clone on github. You can search it.

Yeah, not just SDK as kenny said
everything is being reconstructed

did you use ENV_DX9/Conquer.exe as you dll entry point and looked at the external dll imports going from there to see the flow? Because I am currently trying to reverse it so might benefit from your experience

Yes and no 

i did use the exe's decompiled output and its imports/exports/xrefs as a starting point to understand the overall architecture, but rather than purely tracing imports live from a running exe i worked from static analysis, Ghidra and Binary Ninja decompilation of both the exe and each individual DLL.

then built a dependency order that maps which DLLs depend on which, so reconstructed bottom-up foundational DLLs first (like graphic.dll, GraphicData.dll) before higher-level ones (like Role3D.dll, RoleView.dll)

it was so hard at the beginning but when you have working peaces it's only fixing bugs, and fine tuning what already built. and i gave myself some time to make sure all major dll files are reconstructed and made some tools to test the builds with game client files and folder before implementing these on the actual reconstructed exe.

Thank you, that helps a lot!  Goodluck with the rest of scope!

- Replaced the old DirectSound engine with miniaudio
- Refactor the whole sound system and core to better and modern logic
- Made sure music, sounds are working
- Implement a basic effect audio 
- Modified client structure to keep every dll and the main exe inside bin/64 folder same as the classic conquer one doing
