Well we're coming up on about 4 years since Drifter's tutorial and my improved IDA script were posted here, but people still consider being able to update gamedata one of the arcane arts, even without any signatures involved.
It's also about 1000X faster than IDA is if you're just after a quick offset.

The source for the binaries linked on the main page is the same as used for SourceMod's automatic gamedata checking, so should always be pretty up-to-date (hopefully avoiding problems with similar older attempts), but you can just drag-and-drop any .so file.

Couple of things on the wishlist (dylib support and proper history / navigation), but this has been sitting for too long already, so have at it!
Browser support: You get what you get. Latest Chrome and Firefox are fine at least.

PE binaries do not contain symbols.
Like the IDA script before it, this does best-effort reconstruction of the Windows vtable layout using the Linux one (and it's good enough to get even CTFPlayer::GiveNamedItem, which is one of the more complex).

Is there any chance to make this compatible with goldsrc dlls? I have tried it with "cs.so" and the result is

You should open an issue on GitHub and I'll take a look when I have time.

I'm able to do signature scanning quite well but for some reason vtable stuff is black magic to me, this sure is going to help out alot

Thanks

The irony is that finding signatures is easier than finding offsets, especially for windows.

Great work as always asherkin.
