I think this is okay to ask here...? No hard feelings if needs to be removed! 
Reading a recent story about how a batch of PAL copies of Pokemon Omega Ruby and Alpha Sapphire have been breaking over the last year has reminded me once again that all physical matter is limited, and that I should look into making a digital backup of my retro game library in preparation for my eventual upload to Skynet.
With so many forms of (proprietary) physical media though, this is no small task. PS1, PS2 and Saturn games can be dumped with a CD/DVD drives and a PC, but outside of these examples everything gets more complicated.
I've read that more recent consoles running homebrew apps can often dump to an SD card, e.g.:
Dreamcast - can backup DC games with an 3rd-party SD card reader that plugs into the serial port
3DS - can backup 3DS and DS carts to the mounted SD card
Wii - can backup GC, Wii and even GBA (though not GB/C) games via GC-to-GBA link cable to the mounted SD card
...but that leaves a lot of older formats in the dust. I've seen monster cart-readers like this one but 1) that's a lot of money and 2) there doesn't seem to be one go-to recommendation among the many options.
So, for anyone who's done this sort of thing, what hardware did you use for all your consoles?
