Games will typically clear both banks on start and exit. However, if a reset occurs during a game that is using OPL3 features and sets new and connection regs, the next game may be OPL2-only and not clear the second bank as it doesn't exist on the OPL2.
Not resetting the other regs in the second bank is fine as the envelope for all operators gets reset to the RELEASE state.
