r18254 Wednesday 3rd October, 2012 at 03:00:41 UTC by Angelo Salese
Added irq ack to Shanghai 3 HW [Angelo Salese]

Fixed M68K and hooked up SCREEN_RAW_PARAMS for Blocken. Game was definitely running at erratic speeds before [Angelo Salese, Tafoid]

1111TODO:
12all games:
13- Blitter needs to be device-ized
1214shangha3:
1315- The zoom used for the "100" floating score when you remove tiles is very
1416  rough.
r18253r18254
1618- Unknown writes to sound ports 40/41
1719blocken:
1820- incomplete zoom support, and missing rotation support.
21- attract mode tries to read at 0x80000-0xfffff area, returning 0 in there
22  freezes the demo play for some frames (MT #00985). For now I've returned $ff,
23  but needs HW tests to check out what lies in there (maybe a ROM mirror).
24- how to play screen is bogus, it basically doesn't follow the ball at all.
