Okay, @Kazuma77 - the latest commit should fix most, if not all of the annoyances you just pointed out.
Yes, I think you fixed all of my problems. I did still get the error message for there being nothing to archive, but it builds GM9 with the ''data" folder empty, and that's all that matters. And I was able to build an SSR with the flavor changed (I just created a zero byte file for the splash file, since I'm not concerned about being flashy with my "apps"), and it did not include the "README.md" file (and the point was not that the file could not be displayed, so much as that your average autorun script is not going to use it). Problems solved. I hope you'll get these added to your new "ifelse" branch soon.
Just one tiny thing. In the "README.md" file, you listed drive V: as X: Not that this affects me one bit, but I thought you might like to know.
I have a request. An undo combo. You should be able to undo actions, probably up to about 5 actions ago. I could especially use it after I accidentally deleted my title folder in SysNand SD. I'd be fine if the action undo cache is cleared on reboot, as long as you can undo. Preferably also a redo.
Also, a question. Where does GM9 get the System Info (in Home...More...System Info) from?
You already got your answer from d0k3, so I'm inclined to say "Use the backup script, Luke" (or the "Nand Manager" app when I put out R10 of my AIO). However, while a recycle bin is clearly out of the question, an undelete function that works similar to the way Photorec does might be handy to have (after all, you never know what condition a 3DS you find, or have brought to you, is going to be in).
