Button Icons/Logo

I know there is somewhere to find these but i didn’t know what to call of them or where to look, so i apologise in advance.

Anyway, i want some punch/kick button icons fora retro template design (SFII) for a Madcatz TE stick, wondering if there is anything suitable around ?

Thanks in advance

check the trading post, someone already makes decals that fit into seimtsu buttons
