The GameSir Pocket Taco delivers an authentic Game Boy experience on iPhone, though its single-purpose design means it's not for everyone. This Bluetooth controller clamps onto your phone and wakes automatically when opened, offering tactile clicky buttons for retro emulation. At $34.99, it's an affordable way to relive classic gaming, though you'll want to stick with simpler titles from the Game Boy, GBA, NES, SNES, and some DS libraries.

GameSir went with the classic handheld form factor, which captures that nostalgic feel but results in cramped buttons for adult-sized hands. The 600mAh battery easily handles play sessions, and there's even a charging cutout so you can power your iPhone while playing. The controller uses a clever hinge mechanism that connects via Bluetooth the moment you unfold it, though it only works with iPhones—not iPads or standalone Bluetooth mode.

The biggest tradeoff is that the controller blocks the bottom of your display, so you have to remove it to navigate menus or swap games. This makes it strictly an emulation tool, useless for modern iPhone games that rely on touch controls or full-screen action. For retro gaming enthusiasts willing to accept those limitations, it's a charming accessory that captures the Game Boy spirit better than any capacitive button skin could.
