Well, I also use it for other old terminal apps (BBS games), and the remapping of characters was fun too, using unicode to make certain features more distinguishable. (Only downside is it messes up the crystal ball, if you remapped that char, since it wants the standard values, but you can just use memorised values or turn it off temporarily)

The unfortunate thing is the "lag" is a bit annoying with some apps, so I'll probably still use the python2 one for now.

oh. and, using 2 did silence the warning, but performance was still bad compared to python2, and it still requires ctrl-c to exit
