I decided to spruce up the game I had so far. Instead of turning the grid a color for wins, I decided to put in a message saying who won whenever they did.
The X in "X WON" is sprite 0. Since I didn't have much room to work with, I decided to just make a sprite mimic a character. It certainly made things a lot easier. I was having trouble trying to make the game decipher two separate key presses. I had to give up, and instead to start the main game (the tic-tac-toe thing is a minigame), you need to press fire on the joystick instead of pressing x on the keyboard.
I started work on this last night. I worked and worked until at least midnight. I wanted to attempt to put in a second key press code but it was after midnight and I figured I could just do it when I woke up. So I went to sleep.
I woke up at around 11 a.m. or so and continued. That's when the trouble started. Until about 1:30 p.m. when I realized I could start the game with a fire press instead of pressing x. I don't have any more room except for minor changes.
