Hiya - first post and I'm immediately asking for help. Tssk.

I'm drawing sprites to the screen, and some random colours are being displayed as black rather than the colour they are set to in the editor. However other sprites are displaying these colours correctly. Nowhere in my code do I use pal() or palt(), so although I'm assuming it's a transparency issue I don't see what I'm doing to cause it.

Thanks in advance

And ignore me, this was the cause...

"- The bottom half of the spritesheet and bottom half of the map occupy the same memory.
// Best use only one or the other if you're unsure how this works."

And I was trying to use both.

i was actually confused by this the other day and tried to find exact numbers but wasn't certain. just to make sure, does it mean that sprite 128 and forward are aliased with map values where y is at least 32?

Yes, I think that's exactly what's happening. You can have >127 sprites or a map.y >32 but not both.

Actually, you can use a piece of the given memory for each. I used the left half of that for sprites so I'd have some more and the right half for room layouts for a game.

@betoraposa - that's good to know! How's it done? I could see a way of setting where it got sprites from.
