Hi guys i found this unpacker and its working!

http://www103.zippyshare.com/v/8xt2nmEr/file.html

all names write in lower case letters

example:
if file name is "SOUND.LIB" write this name in console "sound.lib"

I know iron3d.dll is a core of game sourcecode.

All .dll files can be edit with HxD but its pretty hard.
