It is convenient to work in that way, enabling "warp speed" to cut loading times and starting over and over again as needed :-) Best regards, Marko PS: If you can produce a .tap image of the game, I am willing to take the challenge and document the steps that I took. PPS: I have sometimes found watchpoints (memory read/write traps) useful when debugging this kind of problems. PPPS: I wonder if the VICE guys have ever thought about implementing something similar to Valgrind Memchecker to catch access to uninitialized or unaddressible memory. For example, some Vic-20 cartridges seem to expect that RAM is initialized in a certain way. Cosmic Cruncher springs to my mind.
