There are various "fantasy consoles" people make video games on, like the piko-8^1 (which the indie darling Celeste was originally developed for) and the TIC-80^2 (Providing a more PC-like experience). It might be best to think of them as emulators for computers/devices that never existed. Some platonic ideal of game consoles past. They're often programed in LUA and provide limited RAM/Display-resolution/palette-depth, etc, in order to provide a retro feel while not requiring you to program in actual assembly.
Personally I'd be more interested in this as a field-device/development-environment/tricorder type unit. It seems like a great unit to hook a chip programmer up to, or one of those open-source FPGA-based oscilloscopes, or other lab instrumentation.
