I'm working on some more maps from Yoshi's Island, and fixing my old maps. Adding backgrounds on the 2-4 map is hard, because the default color that ZSNES makes as the background when you disable all the layers is used in the level, but I'm working on it.

Games I have mapped--Zombies Ate My Neighbors (SNES), Mario Party 3 (N64), Super Mario Bros Deluxe (GBC), New Super Mario Bros. (DS), Mario Kart DS (DS)
