Assuming that all initialization routines are invoked directly by the RESET handler (and not i.e. by an interrupt handler), you could run the code in a generic 6502 emulator, which doesn't need to know anything about the hardware. That emulator could then log all reads and writes to e.g. $0800-$BFFF. Unfortunately I don't know such emulators very well; you might need to do some C programming to adapt e.g. the CPU emulator VICE is using. I used a modified version of a VIC-20 emulator to remove the copy protection from a couple of very tricky cartridges. Marko - This message was sent through the cbm-hackers mailing list.
