And to be super cheeky, do you have the source for luaeqg.dll available? :D

Not sure about your compile issue. I know IUP is a bit of a pain to set up and has different lib/dll versions for each msvcrt -- I think I made it on VS2010, so that might explain why 2013 wouldn't play nice with it as is.

I might see if I still have the source for luaeqg around but it's just some poorly-written stuff for opening S3D and WLD files. I have some better classes written for that stuff now, and if I made any future tools I wouldn't need the DLL at all...

Anyway sorry to take so long to reply, working on a different project lately!
