X vs. O

Chris!

I thought a game about warring letters would be fun. I attempted it a few times but nothing ever came out correctly. Sure, they worked, but it didn't seem FUN. So this is my third attempt at a game like this. I thought since it's a war between X and O that I should put in a Tic-Tac-Toe minigame in it. To access the minigame, press o on the keyboard during the title screens. A blank board should come up. Left controller controls X (and always goes first), and right controls O. If X wins the grid turns green and if O wins the grid turns blue. In case of a tie, the grid turns red. At the end of the game, you can press o on the keyboard to start another game. If Tic-tac-toe has already been done for the Odyssey2, oh well, I spent days working on it.

Tic-Tac-Toe hasn't really been done yet, AFAIK.  There is Noughts and Crosses, which differs in that you only get three of each character, so for your fourth move (and beyond) you have to pick one up and move it.

I noticed the bug from the first one, but it looks like you fixed it with the latest version.  I had the game completely freeze once, but I couldn't reproduce it.

Did the game freeze in the latest version?

Yes, it did. I have a new version which I tried. Let me know. Take a screencap if you can. (Prt Scr button on the keyboard and then open Paint and then Copy it in there.)

It looks like you solved the freeze. Nice work.

One time I had a game restart without pressing the letter o on the keyboard. I don't know why.

I decided to toy around with the game's code some more.

I thought Battlezone would be a good fit for the Odyssey 2. But I'm having trouble trying to get the illusion you're going forward. What do you think?

At a good stopping point for now. To get to the O shooting game, press x on the title screen. To go to the 2-player tic-tac-toe minigame, press o. I plan on putting more stuff in the o shooting game. And apparently "clearchar" doesn't clear quads? What's that all about?

I think clearchar only clears the characters because the programmer wanted to undo only what the BIOS prints: SELECT GAME.  There are a few other things that seem like there could have had more forethought in the BIOS.

Why does every game start with SELECT GAME anyway? I think it's kind of unneeded if there's only 1 game, like some have.

I think it's even stranger when the game box would say "Multi-Mode Game Cartridge" when there was only one game with only one mode on the cartridge.

It's Philips' welcome screen >:D

Perhaps Philips had wild plans for later. Although I think there just needed to be a home screen and no one really cared about what it looked like. The home screen is the same for all Odyssey, Videopacs and derivative consoles, right? Or are there any differences between them?  :-\
