Summary	06908: bbhcotw, bbh2sp: Game runs slow on certain levels despite being 100% in MAME (snow?)
Description	On certain levels, the games will run very slow despite MAME reporting 100% speed with F11. This happens in Canada which has a snow effect. Tried an older version (0.180) and this did not happen. Could no reproduce in bbhsc or bbhsca.
Steps To Reproduce	Start a game and press F11 to show the game speed. Go to Canada and play through some of the levels. No need to shoot, just observe the speed of the animals running in relation to the speed MAME is reporting.

No.14855 tedgreen Developer Mar 18, 2018, 19:24	Thanks for putting this issue up. I had made an earlier commit which made the voodoo video timing correct which exasperated the incorrect cpu frequency setting.
