Intro displays black bars once music starts.

[YLFAndy]

Playing a number of the MRAs results in black lines appearing in the opening scene when the music starts (they disappear as soon as the music ends).

Repro Steps:
Launch an affected MRA (ex: Teenage Mutant Ninja Turtles (Oceania 2 Players, version ), but a number exhibit the behavior)

Result:
Black lines appear in the solid color portions of the opening sequence (see video below)

Expected:
No corruption.

If this is a duplicate - I couldn't find it in the issues list - please close.

Thanks for the detailed report. Probably related to the SDRAM data clash causing #4 .
