I gave it a shot, and my best guess is some sort of basic extension. I see several calls to $0070, and lots of calls to random places in the basic roms (I can't be more specific than that). Also, the code blocks are very disconnected, meaning there's not a lot of cross-linking between the bits of code, which suggests that most of the little routines are being called into from outside of the rom block. There are 0 calls to the traditional kernal i/o routines. No jsr $ffcf/e4/d2. One call to $ffcc, and one to $ffc9, but no idea what .x is at that point. Anyway, this was my very first time trying to do something like this with a rom, so I'm certain someone else could do better, but that's my guess. - Bo On 10/10/2017 4:48 AM, Francesco Messineo wrote: > Did anyone try to disassemble this dump?
