ccastles.c

0.26 [Pat Lawrence, Chris Hardy, Steve Clynes]


VIDEO HARDWARE NOTES:

- Crystal Castles doesn't have a color PROM. It uses RAM to dynamically create the palette. The resolution is 9 bit (3 bits per gun). The palette contains 32 entries, but it is accessed through a memory windows 64 bytes long: writing to the first 32 bytes sets the msb of the red component to 0, while writing to the last 32 bytes sets it to 1. The first 16 entries are used for sprites; the last 16 for the background bitmap. I don't know the exact values of the resistors between the RAM and the RGB output, I assumed the usual ones.


Inp:

- ccastles: Playback doesn't work correctly unless sound is disabled when you record them. inp061ora


WIP:

- 0.26: Added ccastles.c driver.
