Blue MP Digits patch?

Good observations, it might uses those bytes but I never checked. It's best to use unpatched ROMs with Editors to avoid issues.

Oh, sorry - I edited my post after you read it.  As it turns out, the bug was related to Panda's scroll animation fix (with Gau's rage).  I applied both patches at the same time and didn't expect such a simple patch to cause that error, so I assumed it was the Blue Digit patch (never make assumptions, eh?).  You should read my previous post again for other information I added, however!
