I am a person who will randomly contribute something sometimes.
This page looks terrible because I'm trying to figure out how to make pages and stuff.
-Unused "Yoshi Drums" for Noki Bay from Super Mario Sunshine.
-Unused Frog Mario Sprite from Super Mario Bros. 3 (NES)
-Unused boss fight tile from Super Mario World (SNES)
-Unused Lurchin sprites from Donkey Kong Country 3: Dixie Kong's Double Trouble*
-Unused Dixie and Kiddy sprites from Donkey Kong Country 3: Dixie Kong's Double Trouble*
I also made the page for Pac-Mania (Arcade), and found unused sprites from it. http://tcrf.net/Pac-Mania_%28Arcade%29
* I did not have a TCRF account at the time these were added, but I actually ripped them in the first place.
