WASM-4
The WASM-4 is a fantasy console developed by Aduros, similar to the likes of the Pico-8 and TIC-80. It was released in 2021.
WASM-4 runs games written in WebAssembly, which is compatible with a wide variety of programming languages (as long as they compile in WebAssembly). This fantasy console is opensource and distributed on Github.
The specifications should be mentioned in their respective sections, not here in the summary.
