I tested the latest release on openmsx on the same miniPC with the same keyboard.
In basic, apart the usual mismatch between the Italian keyboard and the Japanese keyboard (I tested a TR-GT), there were strange random problems. Some keys (including enter and '.') stay pressed or start being pressed randomly.
The 'usual mismatch' should not be relevant on openMSX, because openMSX tries to fix that by translating the character that the user intended to type to proper keypresses on the MSX.
So, can you elaborate on the 'usual mismatch' problems?
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.
ALL CHANGES:
* 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.
Made an emergency release of fMSX-Android 3.6.13 today, fixing possible buffer overflow problem in the native code and adding extra 15fps when showing screen in "Soften Video" mode:
