I have released fMSX-Android 3.6.12, a new version of my MSX/MSX2/MSX2+ emulator:

Starting with this version, you will be able to find stuff printed to the MSX printer in the /sdcard/fMSX/PrinterOutput.txt file. I have also fixed the SHIFT key on the physical keyboards and added support for two missing Xperia Play buttons.

Directed MSX printer output to /sdcard/fMSX/PrinterOutput.txt.

Fixed SHIFT key accidentally triggering N key.

Fixed support for Xperia Play FIREA and FIREB buttons.

Added sort-by-date mode to the File Selector.
