Take a look at the attachment. The "pot" here is initialized to zero. Which of course can be changed if you prefer. The new version is even shorter than what's in the ROM, and it requires only R00..03. How do you like it?

That is: once it is defined when exactly a new game starts (I'm not familiar with this kind of devices). We can also save R05 in the ART program – unless the shot counter is recalled somewhere, e.g. at the end after the KILLED message. Or we add a max. number of shots. ;-) (12-04-2016 08:55 PM)Gene Wrote: Tic-Tac-Toe – LBL “TTT” – Flag 05 is set in line 06 but never tested or cleared in the program. ?!? – Flag 05 is the "first move" flag which is tested a few steps after LBL B: 32 FS?C 05 33 GTO 12 The program will not work without this as this step sets the basic strategy. ;-) (12-04-2016 08:55 PM)Gene Wrote: Sum of Digits – LBL “SD” – Label 03 used unnecessarily in line 26. It can be deleted if program is run from ram. Hmmm... I also got a complete rewrite of the SD program. IIRC this was even posted somewhere here in the forum. Dieter |
