Also, I remember a tape copying program that would refuse to copy itself. In other words, you were lucky. > I've tried loading them in Vice 1.9 with full memory > expansion, and they work just fine. According to the PCB scan, the cartridge has six 2114 chips, which makes me suspect that it has a built-in 3-kilobyte RAM expansion. > A related topic: I only have a 16k and a 3k expansion, which sadly > means that I can't use these files with expanded memory.

Alternatively, you could try remap the 16k expansion from BLK1+BLK2 to BLK3+BLK5, but you'd still need to plug in both the 16k expansion and the 3k expansion simultaneously, or the program won't work. The images are now also available at http://www.funet.fi/pub/cbm/vic20/roms/tools/16k/. I optimized the scans with jpegtran, but that didn't make them much smaller.
