My only regrets are that it's a blank screen rather than a crazy glitch screen.(It was the only thing I changed since my last test)
Well, we can't help you fix it if all you're going to tell us is that your rom broke. What is "your last test"? What hacking method are you using? Are you using the latest version?
I was using the Vanilla Skills patch. I got it maybe 3 days ago?
It's also a reasonable guess that it simply didn't play well with all the other ridiculous patches I had
