Why bother with an Everdrive on an Analogue Pocket? Mine has only seen a cartridge once, just because my partner happened to have an old GB game she wanted to see if her save had survived on, otherwise it runs entirely off SD.
I never had a Game Boy, back in the day I was the kid tethered to the power cord with his Game Gear. I almost bought the adapter, but then I realized none of my games had saves so I had no reason to want to use the real carts.
