First, let me just say that I love Multiman, and I hope you don't find it insulting for me suggesting something.
You have made lots of changes over the time multiman has been out, but one thing has stayed the same. And I don't know if it is even possible to change. but the transfer / back up has not changed ( cosmetically ) since the original manager was released.
here is my idea, I think it merges with multiman game setting menu.
I hope you read this, I don't even know if you check this site. I was going to post it at another forum but it seems you packed up and moved your business else where.
here is just a concept of what I was thinking for a update. transfer.jpg
updating the transfer screen might not be a big priority or anything but maybe something to toy with when your bored? dunno, Just a idea.
