Version 1.2 adds built-in BASIC support (thanks to Avery Lee and the open-source Altirra project) which allows a wider variety of games to be played. A few new optimizations. Fixes for PAL sound and framerate. You can now tap the lower right corner of the touch screen to toggle A=UP which makes games that have a lot of jumping more enjoyable with a D-Pad (Alley Cat, etc).
