I do not know if this report is an emulation bug - perhaps it's normal.

No.21533 Balthier Tester Jun 8, 2023, 18:48	Is this different to previous mame versions? Is there actual evidence from a real machine to back this up? I don't understand how this is "Confirmed" without proof.
No.21534 Robbbert Senior Tester Jun 9, 2023, 04:37	Confirmed only indicates that by following the procedure given, that the symptoms can be confirmed. That is all. It doesn't indicate there's a regression or something wrong. Those who are familiar with the game and driver will have to figure that out.
