- It does, but you didn't think hard enough. HAM8 means 6 bits modify value and
- 64 base registers. If you put into those 64 registers all the possible 2 lowest
- bit combinations for all base colors (count'em, 4*4*4=64), when you modify
- the upper 6 bits, you can (theoretically, although getting any one color might
- take even 4 pixels...) use any color from the 24 bit palette.
