Kirby Super Star Sprite Ripping Issues

[Barack Obama]

I tried a bit around and for me, only sprites are visible in vSNES with the level foreground being corrupted. It shows the level tiles for an intro scene correctly, but playable levels just don't work anymore.

Btw I found this level editor for Kirby Super Star Ultra:

Are the graphics identical? If yes, maybe the DS version could be better for background / level rips.
