YES!
It would be cool if people using virtual consoles could keep the same screen ratio!for 128x128 px would become 128 x 115px instead.
i think there is one lua-based fantasy console that supports flexible display resolution, like changing to 160x144 - i forgot which one is (for sure isn’t TIC80)
Pixel Vision 8?
No wait, that doesn't use Lua.
