@ -9,6 +9,8 @@ These games use the custom blitter GA9201 KA01-0249 (120pin IC)
driver by Nicola Salmoria
TODO:
all games:
- Blitter needs to be device-ized
shangha3:
- The zoom used for the "100" floating score when you remove tiles is very
rough.
@ -16,6 +18,10 @@ heberpop:
- Unknown writes to sound ports 40/41
blocken:
- incomplete zoom support, and missing rotation support.
- attract mode tries to read at 0x80000-0xfffff area, returning 0 in there
freezes the demo play for some frames (MT #00985). For now I've returned $ff,
but needs HW tests to check out what lies in there (maybe a ROM mirror).
- how to play screen is bogus, it basically doesn't follow the ball at all.
