Also, it looks like line 968 (#65) and 990 (#35) are constants that can be put at the top of the file, as are 889/903 time delay amounts (in the -03 ROM). line 835/837 is interesting. Wonder what is going on there. lin 427 says unused, but the same line is in the -01 ROM. Is it unused in both? Was the lack of storing cmd_x to >512 just an optimization? How do they know it is 0 already? Line 283 (#67) looks like another constant. Message was sent through the cbm-hackers mailing listReceived on 2014-07-06 08:01:05
