- Convert the color PROMs into a more useable format.
-
- Pandora's Palace has one 32x8 palette PROM and two 256x4 lookup table
- PROMs (one for characters, one for sprites).
- The palette PROM is connected to the RGB output this way:
-
- bit 7 -- 220 ohm resistor -- BLUE
- -- 470 ohm resistor -- BLUE
- -- 220 ohm resistor -- GREEN
- -- 470 ohm resistor -- GREEN
- -- 1 kohm resistor -- GREEN
- -- 220 ohm resistor -- RED
- -- 470 ohm resistor -- RED
- bit 0 -- 1 kohm resistor -- RED
