Here is my method for preserving old games:

IF PC - keep discs and box, etc... in dark, dry room @ 5-30c (my study)
IF CONSOLE - keep cartridge/discs and box, etc... as above

IF NOT OWNED - keep archive/iso on DVD-ROM & external hdd with boxshots, etc...
WHEN "not on internet" - Upload all to internet.

BUT "CONSOLE" - let someone else do the emulations, as I haven't a clue what to do.

(except for 3DO. I know how to do that, but that counts as IF CONSOLE)

The "significant properties" of computer games to keep are:

ALL OF IT!!!

You can't preserve something intact by ripping bits out of it.
That's just puerile.
