Title: SMB1 - Koopa Troopa Sprite preview problem
Post by: Eden.GT on January 25, 2019, 09:18:39 pm
So I have received this problem by a friend regarding part of
a certain sprite not showing it's full tiles during a certain situation.

Via SMB Graphics Workshop, it can be clearly seen that an enemy sprite consists of 2x4 8x8 tile sections:

Blank tiles of the Koopa will be replaced by the next tile to see the issue:

Now, here's the problem. Whenever Mario knocks a Koopa via brick hitting, the very top layer of the sprites will not show up for whatever reason:

I'm thinking that the top layer sprites have been replaced by the floatey scoring sprites during this situation- but I might been proven wrong. Anyone can help assist the problem/code routine that lays here?

Eden.GT, would you mind sharing your ips? It's hard to see what you are describing.

Just fill in the empty Koopa Troopa sprite gaps with other tiles using SMB Graphics Workshop. No need to share a patch for that. Also edited my last post to clarify what I meant.
