The GPi Case 2 ($80–$90) and TRIMUI Smart Pro ($80) sit at the same price point and share a similar emulation ceiling, handling systems up to PSP on their respective entry-tier chips. The main practical differences are form and ecosystem: the GPi Case 2 is a vertical Game Boy-style shell built around a Raspberry Pi Compute Module 4 running RetroPie, giving tinkerers a familiar, well-documented platform, while the TRIMUI Smart Pro is a horizontal device running Tina Linux on an Allwinner A133 Plus, better suited to buyers who want a conventional controller layout out of the box.
