Summary 04561: Most games in metro.c: Offset screens and/or misplaced graphics
Description In many instances of games in the metro.c driver, there are backgrounds which do not match up with gameplay, misplaced in-game sprites or other graphical nonsense. Seems to effect the horizontal games in cases where the screen is moved up and off-screen.

Some examples include: mouja, pururun, toride2g among others

 IRQ generation is quite a mess on metro.c, and I really think it would need some HW tests.

 I'd say this was critical, it renders several games completely unplayable

 I'm not gonna argue if it's major or critical, but yes it's a bad bug and should have high priority to fix it.

Anyone notice that ladykill start button doesn't function anymore either?

 I had a look to see if it was fixable, and have to say bah bah bah this is the worst collection of irq hacks in a mame driver I've seen. It's unfixable in its current state.

I wouldn't say it's a regression, Kale is not to blame here. metro.c basically evolved into this over the years as mame coders were trying to fix individual games. I think it's best to remove all irq related code and start from a clean slate.
