Inside the Pocket Taco are soft silicone pads on either side that grip your phone without damaging it. The ergonomics aren’t as good as standalone controllers, but the Pocket Taco is quite comfortable to play with. A hard plastic carrying case is included, but the Pocket Taco is a bit too thick to be comfortably pocketed. I primarily tested the Pocket Taco with Game Boy, Super Nintendo, and GBA games played through the Delta emulator and RetroArch on iOS. When I first tested the Pocket Taco with Delta, I turned off the emulator’s default skin to remove on-screen controls.
