Fixed version

An error in the Mega Drive version's palette storage results in the game appearing darker than it actually should be. On the Mega Drive, the bit order of palette colors is 0000BBB0GGG0RRR0, with RRR, GGG, and BBB being the red/green/blue components of the color, and 0 being zero bits. This game, however, uses 00000BBB0GGG0RRR by mistake; the lowest bits of the components are ignored by the hardware, resulting in a color range (000, 001, 010, 011). Because smaller values are darker, the colors will thus appear darker.

Not fixed in any version.
