Originals: CAPSify them and get them preserved. Use WHDLoad to install thm and use them.
Copies: ADF'em and get them preserved. That is, if there's anything you have that it's NOT in TOSEC.
For other platforms: Do whatever is similar to the Amiga counterparts, shame is, in most formats, there's nothing like CPS. What bout C64 software for example? That should die sooner than Amiga software, don't you think? And no one has come up with a CAPS-liek solution for this
