-
- Convert the color PROMs into a more useable format.
-
- Green Beret has a 32 bytes palette PROM and two 256 bytes color lookup table
- PROMs (one for sprites, one for characters).
- 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
