If you try to load the game from MOS 3.5 the game crashes (with a corrupt screen image of the title) after the title page and music (before the actual game starts). Switching to MOS 3.2 (with the exact same Master 128 configuration) works perfectly.
Another odd observation: When I plugged in a ROM cart (containing a BeebSCSI ROM in slot 1 and HiBASIC editor in slot 2) it then booted and ran ok from MOS 3.5.
