Megadrive binary outputs should be 16 bit big endian #42

The VDP only allows 16 bit writes and the m68k CPU is big endian. Currently, using SGDK for example, binary palettes and tiles from Superfamiconv are uploaded to the VDP with the bytes swapped.

@est77 Does this only apply to palette data, or maps/tiles as well?

If I remember correctly it happened with both colors and tile data. It should be easy to do a quick test converting known colors and tile data and see the endianess of the output.
