About

MicroW8 is a WebAssembly based fantasy console inspired by the likes of TIC-80, WASM-4 and PICO-8.

The initial motivation behind MicroW8 was to explore whether there was a way to make WebAssembly viable for size-coding. (Size coding being the art of creating tiny (often <= 256 bytes) graphical effects and games.) The available examples so far are all in this space, however, I very carefully made sure that all design decisions make sense from the point of view of bigger projects as well.

Specs

  • Screen: 320x240, 256 colors, 60Hz
  • Modules: Up to 256KB (WASM)
  • Memory: 256KB
  • Gamepad input (D-Pad + 4 Buttons)

Examples

Examplers for older versions:

  • Technotunnel B/W (199 bytes uncompressed): A port of my entry in the Outline'21 bytebattle quater final (older MicroW8 version with monochrome palette)
  • XorScroll (50 bytes uncompressed): A simple scrolling XOR pattern. Fun fact: This is the pre-loaded effect when entering a bytebattle.
  • CircleWorm (126 bytes uncompressed): Just a test for the circle fill function.
