Runtime Error 005 with Tyrian 2000 in real MS-DOS May 18, 2017 18:59:14 GMT Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by rogueai on May 18, 2017 18:59:14 GMT I get Runtime Error 005 whenever I try to run any of the exe files with Tyrian 2000 in a real MS-DOS system. I've read about people getting runtime errors with too fast of a CPU but mine is only 90mhz.
