Debug Symbols Questions

[rcrrad]

Hi, I'm curious about how was it possible to get Diablo executable function names dump? I can not find any binary that has such information included; symbols are stripped.

Like this:

D3::UIManager::HasUIElement
D3::UIManager::IsInitialized
D3::UsePowerToActor

IDA didn't find the function names, how people did that? Is there a PDB file or something? Thanks.

Ive heard that the original beta had debug symbols, but its also plausible people reversed each function and named, then its easy enough to use ida and patchdiff to match them up each new patch.

Personally i used one of the lists off the forums to name all my functions, then each patch just use patchdiff to move them across to the new exe.
