Let's see.
Buster Sword - Final Fantasy 7
Pokeballs - Pokemon
Triforce (second appearance?) - Zelda
L Block - Tetris
I assume the pink crystalline heart and the wand high above the Triforce are references to some other games, but I assume I haven't played them.
It's always nice to see easter eggs hidden about. Back on the SNES, the only ones you could really spot - if you tired hard and were actively looking for them - were bizarre faces hidden in the middle of nowhere...
