Good question lol. I have no idea. The MP one was a really really easy tidbit. You just change 2 bytes "11" to "22" and it works. There's 1 glitch in battle with weird symbols but hm...That's actually a really really good question.
Edit: I'm having troubles doing it with Level, as it's a bit different. And I have no idea where the Time data is stored via hex, so idk there either. I could probably find the time data very very easily...but too lazy atm.
