Allows Coins and Yoshi Coins to be collected with Koopa Shells. Read the .asm file for more info.
It's also compatible with the Yoshi Coin Fix and the Individual Dragon Coin Save, but note that you should insert this patch after instering any of those two.
Note that due to the way sprite/object interaction works in Super Mario World, coins placed next to walls can sometimes not be picked up. I tried as much as I could to alleviate this but I couldn't really fix it.
Update 1 (Juny 8th): added support for buzzy beetles and throw blocks.
