Retroid Pocket5 Retro Handheld Game Console, 8+128G, 5.5-inch Touchscreen 1080p Portable Android Gaming Handheld with Adreno 650 GPU & WiFi 6/BT5.1, Snapdragon 865 Processor, Android 13 (Black)

This thing is a beast, it can handle more than I thought it could. You can emulate pretty much everything up to Switch. You can even play PC games on it if you know what you're doing. The potential is really amazing if you take the time to tinker with it. But even if you don't tinker much you can easily set it up to play lots of old games. Also great for native Android games. The screen is incredible, so vivid and bright. Ergonomics could be better but it's still fine, you can buy or 3D print a grip if needed. Body feels very premium. Just such a great little device, worth every penny.
