Speed back to dolpihn: - Revert Read16 CPRead fifo hack for fix RE0. This hack only solve RE0 but brings slowdown in games like RE Umbrella, etc. - Move isFifoBusy again in the fifo loop and use s_fifoIdleEvent for AbortFrame. Note: if you can play RE0 only deactivate PanicAlert. These opdecoding error seems harmless. Some day this wiil be fixed in right way.
