Possible Error/Bad-Instruction in Gecko Code Handler for C0 Code Usage

[Vega]

That's a Decrementer Exception (0x80000900). Either find the Broadway manual on the web somewhere (can't post it here), or find some generic PowerPC article about handling exceptions.

My uneducated half ass guess is that something with the code handler (via C0 usage) is messing up r13's value? And r13 should NEVER be modified.
