I was wondering about this too. Then I realized that the interpreted nature and user friendliness doesn't map to a low power mcu. You either settle on a hardware that's basically an embedded linux that's way overpowered and runs hot/drains battery OR you let go of the ease of use and get dirty with embedded development tools. If you look up some GBA homebrew you can quickly see why this will remain unpopular. The third and most ridiculous option would be fabbing a custom low power SoC that has an embedded gpu specifically designed around the pico8 limitations and some extra opcodes that accelerate luaJIT.
