More work. I'm at a good stopping point for now. Everything works good. I'd be happy with just this as a game, but I'd like to add more stuff in the main game. And I have the room to do it too. Not so much in the tic-tac-toe bank. Apparently "clearchar" does not clear the quads (score), so the score of the main game was showing during the tic-tac-toe game. I had a real hard time trying to put in score clearing code. I was just going to omit the word "tie" when a tie happened, but then I noticed a little patch of code that wasn't being used any more. So I replaced that with the tie displaying code and it works!
I think it's going to be just the tic-tac-toe game and the x shooting o's game unless I can fit in some code in the tic-tac-toe bank to put in code redirecting it to a third game in a different bank, but I don't know if even that will fit.
Stayed up working on this thing then spent an hour laying there trying to go to sleep. FInally got to sleep at about 4 a.m. or so. I woke up at about 2 p.m. and worked on the code some more. But I'm sick of working non-stop on this game so I'll quit for now and pick it back up soon.
I tried it on an Odyssey 2 and it works great. I only have one SD micro card converter so I thought I lost the card I had with my backup stuff on it when I switched it to the card that I had all my Odyssey 2 games to put in the Odyssey 2 flashcart. But I found it. My question is why do they have to make stuff so freaking small? A micro sd card is tiny. And it's a really big wonder how it fits GIGABYTES of info on it. Really blows your mind when you think just 60 years ago we had none of this.
