08fdc65d69 [C64] T65: detect IRQ even when not RDY 
Fixes Tsunami demo

Waiting for RDY while the interrupt already asserted causes too much
delay. The interrupt cycle will still start at the correct position,
as soon as the RDY line is de-asserted, and other conditions are satisfied.

2aab723f24 C64: [VIC2] Fix sprite priority by vpelletier 
If a lower-index background-priority (1) sprite's opaque pixel intersects
with a higher-index foreground-priority (0) sprite's opaque pixel, and the
screen bitmap has a foreground color at that same position, then the
screen bitmap's foreground color is visible.
This is counter-intuitive, as higher-index sprite's pixel alone would mask
the bitmap color, and adding another sprite top of it makes the bitmap
visible again, but this is how the VICII works.
