From what I understand about this app your english translation is pretty accurate, but I think it will be even more so if you go for that option someone suggested (for the compatibility tab): "target", "source" and then "make compatible using source's ID". That will make it even more understandable than the original french version.
As for the "protection" tab, I'm not sure since I don't know much about .sfo files, so this should be confirmed by the dev behind this, but I believe it's more about "ID lock" and then "Lock" - "Unlock" than "Protect", "Unprotect". Again, maybe
will soon give us a more detailed explanation that'll make the translation easier.
"Mister President, I haven't taken a shower or a dump for ages, but I can still protect you..."
