it's literally a screen when running the game that is titled kernel panic. i believe it has various values in the different registers that would be in the hardware to help troubleshoot, but that degree of troubleshooting is beyond me at this point in time. I'm fairly certain it has to do with how I have my battle system designed. I think for longer battles, it's keeping too much in memory and ultimately runs out and is unable to continue which crashes the game. I'd post a screenshot, but I'm trying to redesign things so it's a bit more modular and hopefully lightweight.
Edit: Here's a capture of a kernel panic. I seem to get it every 9th or 10th battle action.
