In the case of this investigation, either will work, because the problem is the Kernal ROM, not the BASIC ROM - BASIC isn't running at this point. The game uses the IEEE routines and the editor routines, all located between $E000 - $FFFF. Thanks to all who have made suggestions here. I just was _not_ getting the syntax from the help files. I should be able to crank through it now. I would have fixed the BASIC 4.0 problem years ago, but the breakpoint system wasn't sophisticated enough to aid me. Now I just have to figure out why I'm having line-wrap problems on a machine that I thought used to work. Once I'm done, I think I'll turn my attention to supporting the 64K RAM board. It's in VICE now, and someone recently gave me one needing a little restoration (missing pins in the CPU cable). Between the remainder of the 32K of RAM above the game engine (about 22KB) and the extra memory card, the program might be able to nearly entirely buffer some of the smaller games. Less disk I/O means faster game! At least the IEEE-488 drives are noticably faster than the 1541. -ethan -- Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html Message was sent through the cbm-hackers mailing list
