The VG Resource

Emulator is bsnes-rawpalettes.

The chameleon sprite below is bopping up & down, but also stretches vertically while doing that. It does that even in Tile / Sprite Viewer:


Summon Spirits - Luna & Origin:

These two have the exact same effect, but I have no idea how Smithy ripped their original unstretched sprites.

Here is a bsnes quicksave from the scene above:

Has anyone an idea what to do here?

Is the stretching also in the tiles in the VRAM?

Yes, the vertical stretching also appears in Tile and Sprite Viewer of bsnes-rawpalettes.

If I enable Auto-update, I can see in realtime how the sprites resize in both viewers.

Here is a HD video which shows pretty clear how it looks like:
