it's actually pretty usable! and with dosidle, it doesn't take up 100% cpu
though if you do anything graphical, like run windows, or render things to the screen in qbasic, you need to switch to vnc
it would be so cool it you could use sixel with qemu so it would all work without! (i wonder how hard it would be to compile the sdl backend to work with the package?)
(i mostly set this up to play around with @Nodocchi's dos and win16 shenanigans!)
