Yeah. Exactly. I found the info that explained the system, but it was too late. :D Thanks for info, though.
This is a 1-bit palette (2 colors, like those old mobile phones have), not a 2-bit (4 colors, like Game Boy has). Doesn't really matter though since the 2-bit palette can include the 1-bit palette in it, but I think that you mean 1-bit instead of 2-bit.
Thanks =)
