I'll try to isolate a fixed version - if that's possible. EDIT: The second time I ran with credits already in there after exiting - I get the reset shown by OP (after about 7 seconds). This isn't fixed then. I'll narrow down a actual regression version then..

No.08385 M.A.S.H. Senior Tester Mar 17, 2012, 15:23	Found 'Fixed' version. You must delete the old NVRAM file first, then start the game with INSERT COIN. After this start the game a second time with the new generated NVRAM. Press FAST FORWARD and you see the game resets.
