If I were having trouble running an old DOS game off of floppies I might try it with an old DOS boot disk, but from other things you have said I wouldn't expect this to help in your case. Still, it's worth a try. It sounds to me as though the copy-protection scheme is getting confused by the 720K disk drive -- probably at the point where it tries to write the authorization to the disk. I messed around with a 720K drive for a while. One problem with them was that they would default to 720K. That might be your problem because.... When you are using a 360K floppy in a 720K drive, the drive will write in the proper format -- *if* the program is using normal DOS function calls. However, if the programmer is doing something tricky with system calls -- like with copy-protection -- then the drive might default to its native 720K format. I remember that there was a way to force a 720K drive to write in the 360K format. There are two problems here, though. First, I'm not sure it would still be effective in this kind of situation. Second, I forget how it was done. It might have been the DOS MODE command or it might have been something in config.sys or autoexec.bat. Or perhaps you can tell your BIOS to treat your 720K drive as a 360K. This would be easy to do. Try any of these suggestions and post again. I'm confident that we can get you playing this game. |
