what am i doing wrong? i cant get castles 2 to play are you just supposed to click the c2cd file? all it brings up is an error "16 bit ms-dos subsystem c:\windows\system32\cmd.exe
The NTVDM CPU has encountered an illegal instruction CS:d36c IP:0000 OP:ff ff ff ff 40
can someone help me out

castles 2 on GOG is configured to run with dosbox.
So please use the shortcuts provided by GOG.
The error you get likely happens if you don't use the GOG shortcuts
