It's a Scratch Sprite Emulator (scratchsprite by me) where you can run .sprite3 games! Or you can move them from your backpack to insert a sprite, go see inside and get a sprite and load it from your backpack or upload .sprite3
Inspired by "MODules" by spybaz template .sprite3: https://www.mediafire.com/file/trgrqf5b7rh5zhl/Funny_Game_v001_ROM.sprite3/file
