A small collection of some CAS images in the STAC system (see http://atariage.com/...covery-sources/for a description of the system)
I'm not familiar how exactly Altirra, and the CAS format can handle custom tape formats. But I recorded these CAS images in Altirra. Loaded them with Altirra and they seem to work fine. You can even test the error recovery if you want.
A handful of "big" titles are included, most of them never published on tape. They were all adapted for a single stage load:
Lode Runner Championship
MULE is, of course, a special case. The gorgeous loading screen was completely omitted. The goal was to produce a "file" that would load with a single stage on a 48K machine, at (almost) all cost. The whole initial selection screen was replaced with a very simple text based selection with just a couple of options. Yeah, almost a crime, I know. But if you didn't have a disk drive at the time, you would die for playing MULE even with those limitations.
Lode Runner Championship was based on the only version I had access then. IIRC it has one or two screen that I think they were corrupt.
