Absolute masochist uses a mismatched pair of old iPods to game on their Steam Deck

pcgamer.com:

Don't do this. For the love of Gabe, don't grab a couple of janky old iPods out of your tech-hoarder's box of old tat and plumb them into your Steam Deck. And definitely don't use them to play Skyrim in the most awkward, hamfisted way since someone last used a baby-doll-in-a-blender to try and beat Dark Souls.

That's the basic takeaway from watching redditor nekomichi (via SteamDeckHQ) doing just that. But, y'know, I've got to say I'm happy they've taken the hit for each and every one of us, so we at least know now to avoid the temptation to put Apple's old music players to such use. Because we've all had that urge, right?

It really is one of the most fascinating things about the Steam Deck; aside from being the device which brought handheld gaming PCs into the mainstream consciousness—and encouraged the big bois of Asus, MSI, and Lenovo to get involved, too—it's also become the tinkerers' favourite toy. It's an eminently affordable gaming device that has been made almost as open as a standard PC.

And because it comes with a Linux distro already installed, it's just crying out for people to mess around with it. And mess around they have, to the point where someone has now plugged a pair of disparate old iPods into their Deck and used them as a combined USB controller. 

In a way it reminds of the time I bought a left-handed joystick for my Amiga to make Sensible World of Soccer more tricky to play when I got bored of perennially winning, because this mod does nothing at all except make the entire experience of playing literally anything on the Steam Deck an entirely horrible one. Though I guess the satisfaction of actually getting the bizarre controller combo to work—despite the masochistic gaming effect—probably does have a certain appeal to some.

So, if you're interested then nekomichi has detailed how they managed to get the iPods running. But essentially they've installed the Rockbox custom firmware onto both iPods and that is what allows you to use them as USB
