My thought was that of debugging in realtime sort of what "C64 65XE NES Debugger" does. Of course that you wouldn't be able to freeze the VIC-II but at least to be able to freeze the CPU and change memory as needed/desired. 15 de junio de 2022 14:48, "Bill Degnan" <billdegnan_at_gmail.com (mailto:billdegnan_at_gmail.com?to=%22Bill%20Degnan%22%20<billdegnan@gmail.com>)> escribió: How about using a HESMAN cartridge to take a snapshot of RAM and then dumping the contents of RAM to a disk? Nothing formal, just what I needed at the time. I documented the process based on the CBM manual https://www.vintagecomputer.net/browse_thread.cfm?id=287 (https://www.vintagecomputer.net/browse_thread.cfm?id=287) I see no reason that you couldn't do this with a C-64 and 1541 drive too, I hope.

Yes, it can. The "CodeRacer"[*] does this and a lot more. * - Vapourware so far due to chipageddon but protos are there ;-)Received on 2022-06-15 17:00:04
