run the door in dosbox with those codes, then MEMDUMPBIN 0:0 640000 or whatever and find where they are in memory (or just search around in the debugger itself) then change the NoBoDy! part and then MEMDUMPBIN again the next run and see what the memory area the ii.. part used to be in changes to? that's how i used Arrowbridge I and II & Betrayal of the Obsidian Baboon to keygen themselves. i would find the old code in memory twice, and then the second run the second spot would have the new code in it for the new sysop/bbs name..

if it's consistent between dosbox debugger runs you can put a breakpoint on the memory location the KEY file for that other program is read to. would put you right where you want to be. i tried putting random data into EZROM.KEY and it seems to be sensitive to the length of data provided.. should give you an idea of approximately what length the data should be. just make it something you can easily recognizing looking at the memory. 000011112222 or whatever.

i like cracking stuff too but the only keygen i made was for LORD 2 .. even though there's a few different ones out there it's still a fun one to work through
