Well, this came out of nowhere. I might consider buying one perhaps… my B-Button is shot on my 3DS XL and I wouldn't mind having something that can play some games again. If a repair would cost more, it'd be worth it.
@nate38 I forgot to check earlier, but the system does still have the outward-facing camera lenses. They're on the bottom half this time instead of the top. Even though there are only a few augmented reality games that used them, they're also used for scanning QR codes, so it's probably for the best to leave them in there.
The SP is the only one you really need. The OG GBA was kinda janky with no lighted screen, open/exposed screen, no rechargeable battery built-in...no need to own that one, tbh. The SP (or SP+) is the one to have. And maybe the Micro if you really wanted (though that has it's own share of drawbacks too).
I was thinking about modding my OG GBA with an OEM AGS-101 (SP+) screen, but then I read that most of them were phonies. Maybe I'll grab the Revo K101 Game Boy clone. It plays original carts, and seems to have some nice features. I probably won't get it, though, because fuck that symmetrical diamond. I LOVED that the GBA only had two face buttons.
