Hello.
I am using Mct 1.83 with OSX.
if I were to send all settings and save to slot 1 ( its the icon next to save to slot 1 icon)
the megadrum would be come unresponsive and can only be recovered by reflashing different firmware than installed.
with windows the problem does not exist.
Megadrum is 644 20mhz encrypted. current firmware is 20100623. the firmware I use to update is 20100801
thanks
