Change Mario's cape position

Hi, I need help with changing Mario's cape position.
I want to change it so falling and spinning while falling Mario's cape animation stay at the same position like it would be if he was on ground.
here are some pictures to show what I mean if I didn't explain it right.

Instead of this :


It would look like this:


picture to show where all of Mario's cape position would be at:


I don't know how I can do that, I did find this in the SMW Memory Map but don't know what to do with it :

ROM Address : $00E266
Length : 44 bytes
Type : Mario tilemap
Description : cape offsets


Sorry if this was a bad post or if I didn't explain it really good, any help would be appreciated.
Thank you.

I think I found the way to do it

I tried this:


I'm new to ASM so I don't know if that looks good but it works I think
It's nice to make wings instead of a cape and it also works when you ride Yoshi
