It's a pity there is not some similar concept using more high level language (instead of assembly).
But I can see why as every interpreted language can be "fantasy console" on itself.
replies(1):
Bedrock is a lightweight program runtime: programs assemble down to a few kilobytes of bytecode that can run on any computer, console, or handheld. The runtime is tiny, it can be implemented from scratch in a few hours, and the I/O devices for accessing the keyboard, screen, networking, etc. can be added on as needed.
I designed Bedrock to make it easier to maintain programs as a solo developer. It's deeply inspired by Uxn and PICO-8, but it makes significant departures from Uxn to provide more capabilities to programs and to be easier to implement.
Let me know if you try it out or have any questions.

I've fantasised about turning LOAD81 into a much more full-featured development/execution environment for years, and have done a fair bit of work on extending it to support other things such as joystick devices, an internal sound synthesizer based on sfxr, and so on .. one of these days I'll get back to it ..
