I have released a new BETA version at
https://github.com/400plus/400plus/releases/tag/20160131-BETA.
Most important change is that now 400plus will write configuration
files to a folder called "400PLUS". You can create such folder
yourself, and move all your files execept AUTOEXEC.BIN there; or you
can let 400plus do it for you.
It also fixes a small bug in the Polish translation.
Hope you enjoy it,
Edu.
