Nice to have this, though I personally find Matt Godbolt's web-based BBC emulator more exciting (and useful)
How does it handle being run on a mobile phone? My main focus with JVIC was to try making it as easy as possible to use on mobile devices, although I'll admit that my testing has only been on Android so far. I haven't tried it on iOS yet.
My Android phone is way too old and slow to load jvic, unfortunately. Let alone jsbeeb.
But works great on my 2013 laptop when plugged into a wall socket!
Every time someone mentions 'ROI' at work, for a split second I'm back at the old 64, not doing my statistics homework.
