No.02799 aaron Developer Oct 13, 2008, 01:25	The problem is due to a PIT timer change that was introduced a while back by Wilbert Pol. Not sure why this game fails.
No.06385 Atari Ace Senior Tester Jul 19, 2010, 06:11	This change in 0136u1 seems to have fixed it. [PIT8253] Update PIT counter even if there was no elapsed cycles (this only affects fast drivers like at586 in MESS). [Miodrag Milanovic]
