Here is an updated version of VUE Snake. It has some bug fixes, a very minor graphical update, background music (a big thanks goes to DanB for his MIDI Player!) and a save feature, which automatically saves all highscores.
Yes it’s best to play it on hardware. The latest Reality Boy has sound support, but Channel 0 is muted (hope this will soon get fixed with a new release), so you can only hear parts of the music from Channel 1.
