yeah, writing back would be great option. I mean it' s been possible for other formats for ages now. though pasti seems to be better that the other formats, it's bad to only have a "one-way street". Especially for people who'd rather use their real hardware than an emulator. And with all this recent work of so many people trying to pastify everything htey can get their hands on, it'd be really a treat to have a "write-back" option.
