If you used my config, press F10 and select the file. You should see 4 files in the default directory that apears Image.d64 caligam1.d64 caligam2.d64 galigam3.d64 Image.d64 is the boot disk. The remaining 3 are disks 2,3, and 4. They are numbered 1,2,3 as gamebase numbers disks from 0, 0 being the first disk. Please let me know if this helps, I am always happy to help... Hope your Vic-20 setup went better than Tempests
