I spotted new version of MD Everdrive but besides some basic info I don't know what it improves over old version. Any games that didn't work on V2 and work on V3? Is it flashing faster? Does this version will pass US region protection from Tempo 32X on EUR 32X addon? I see battery on new version? Why it's installed? Is it previous flash not good enough? Is it fixed version of Monster World IV still works and saves?
