Resurrection!
I've encountered a similar problem for a different game. I don't think there's any control codes involved this time. The game stores the top tiles first then the bottom tiles next. I changed the pointers to allow for more room, but after the 8th character, the game does a line break on me.
Check out the 0's. I didn't do that line break. After every 8th character, the game automatically does a line break. I wanna increase that. Essientially I'm limited with the amount of characters I can have for every string because of that. Any ideas on how I can fix this or even what's the game's doing? I'm guessing the string length is hard-coded.
