Interested in PICO-8 118, it is a fantasy console for creating, sharing, and playing tiny games and other computer programs. You could think of a fantasy console as an emulator for a gaming system that never existed physically.
PICO-8 is basically trying to recreate the spirit of an 8-bit games platform – with all its limitations (128×128 resolution, 16-cols, 32k, etc.) – with a few exceptions that take advantage of newer/modern technology (such as Lua scripting, built-in code/sprite/map/sfx/music editors, powerful exports).
Unlike old consoles, PICO-8 uses Cartridges for storing and transferring games and programs. These single files can even be saved as PNG (image) files containing ALL the source code and resources!
