Yep I just came here to say after messing around with various other options this web app worked absolutely flawlessly with my MZ-RH1, no crashes or funny business to speak of.
Stefano you rock!
Of course, I'd like to add one more vote to the pile for Hi-MD support, that would make these little devices the absolute best retro purchase ever (if they aren't already). Do you think if you had an RH1or similar in hand to tinker with there's a chance you would have time to investigate Hi-MD functionality? Or is it just not realistic time-wise now that things are returning (sort of) to normal?
Thanks a million!
