What exactly is wrong with changing the transparency to a color other than black? It doesn't seem to show up in the game anyway (and why would it? That's the point of a transparency!), so why couldn't it be set to, say, hot pink? I'm asking because of the NPC sprite. It normally uses one entire palette, all 16 colors, to determine from which level it will display a message, but...there are certain levels where I need to use the NPC but don't have
any palettes that aren't already being used. Or, at least, if some of them are free to use in one level, that doesn't mean those same palettes will be free in another level, and I don't want to have to insert the sprite 12 times (once for each palette, minus 0, 1, 8, and F, which the NPC itself uses). So why can't I just use the transparencies of each palette?
