Yes, they all use the same loader and wasteful GCR format. The bytes that are read in are AND'd with $AA, which results in every nibble being either a $0, $2, $8, or $A before two buffers worth of data are sent back to the C64. The loader is at track 17 and always reads tracks 1-25 (skipping 17 & 18) for all of these games. I didn't look at the C64 side of the loader to see how it rearranges the data it receives. Munsters doesn't seem to have any data after track 25, and seems vulnerable to being dumped from memory after loading. I tried a quick rip with SuperSnapshot and it worked fine. The others are probably the same. I didn't see any signatures in the loader that would indicate who wrote it. |
