No.03663 Luigi30 Tester Jan 27, 2009, 21:42	The sounds that make it freeze cause it to hit a STOP instruction at 000806, halting exceution. The instruction is not triggered by the working sound test commands. The instruction set documentation says that processing resumes upon reset, exception, or privileged interrupt. Protection-related, maybe?

I'd suspect if there's an in-game freeze it is not related to the original report. Unable to replicate in-game freeze after half an hour of solid resetting and playing stage 1. So this bug should cover lack of watchdog if anything.
