Peter, Thanks!

It's kind of funny but a friend of mine and I were talking today and come to the conclusion that it was either my 64C had memory issues or most of the D64 out there have been tweaked for emulators. So which chip do you think is bad? The 6510 or the RAM chips. I'm going to take it apart and reseat all the chips and then see what happens. 

Bill, Thanks!

The test I did earlier was take a D64 (64 Demo disk) and copied it to disk, I ran two or three of the programs and they worked. I then copied the disk back to a D64 file and the same programs worked find in an emulator. 

The file I've been testing with can be dled here this is from the the REMEMBER site at It would be great to see if your copy works. 

Your test. I downloaded the file you recommended and copied it to disk. I ran the CBM-* file and it came up with "Waiting for a call" just like in the emulator. The file Blocks used on all the files matched what was shown in DirMaster, WinVice and Disk (is DirMaster ok or should I dl yours?)I saw 2, 39, 4, 4, 5, 6, 8, 8, 8, 9, 9, 9, 9, 9. The Blocks free matched also matched, DirMaster = WinVice = Disk (535 free). Golden13 also ran and created a "Winner Board" and asked if I wanted to update scores.
