Help Analyzing HT3DHeaven.dll and Recovering Its ABI or Functions

Hi everyone,

I'm looking for advice on analyzing a 32-bit renderer DLL named `HT3DHeaven.dll`.

My goals are to:

• Identify all exported functions.
• Recover the ABI as completely as possible (calling conventions, parameters, return types, structures, etc.).
• Identify internal (non-exported) functions where possible.
• Produce the closest possible C/C++ reconstruction of the original code.

I understand that recovering the exact original source is generally impossible without debug symbols, especially if the binary was optimized or stripped. I'm mainly interested in obtaining the most accurate decompiled representation and understanding how the DLL interacts with the application that loads it.

If anyone has recommendations for the best workflow or tools (IDA Pro, Ghidra, Binary Ninja, etc.) for this type of analysis, I'd appreciate the advice.

I can also provide:
- the importing executable,
- the DLL's export table,
- dependency information,
- or screenshots/project files from IDA or Ghidra if that would help.

Thanks in advance.

HT3DHeaven.7z
