Re: Revived Engine - Frank Walter 2.2.0 (Java - WB)

Hi Tirsa Thank you for your efforts to compile a windows version of the library! I have put some effort into compiling it for windows, but I failed. Mostly I had errors loading the library, while your error (the first attempt) seems to be after that phase. Would it be possible to share your dll with...
