If you're looking at gaming replacement parts and modding kits, the first question is usually which upgrade to tackle. Should you protect a Raspberry Pi GPi Case you've already assembled, add HDMI output to an N64 or PS ONE, or replace a bulky original power brick with a modern USB-C power supply? These four products each target a different part of the retro gaming setup, and their listed prices run from $15.50 to $51.50.
Quick take: The GPi Case Protector is the least expensive, no-solder extra. The N64 HDMI Mod Kit and the PS ONE HDMI Mod Kit both need soldering and are aimed at advanced installers. The Universal Type-C Power Supply Kit is the most broadly compatible and requires no soldering.

Product notes
GPi Case Protector
This protector is made for the Raspberry Pi GPi Case Retro Handheld Game Console Mod Kit. The listing specifies food-grade PET plastic, 0.5mm thickness, 95% UV protection, and protective film on both sides. At $15.50 it's the least expensive product here, so it's an easy add-on if you already have the case and want to keep it clean on a shelf. The limitation is that it's only a protective shell-not a console-and the listing notes that the actual protector will be slightly larger than the stated dimensions because it adds clearance for easy insertion. Assembly is tab-style, and there's no hanger.
N64 HDMI Mod Kit
This N64 HDMI Mod Kit includes a PCB, a ribbon cable, and a mini HDMI adapter. It adds an on-screen display, three TV aspect ratios, and eight color modes. The listing says it works with all N64 models except the Pikachu edition. At $39.90, it's $11.60 lower than the PS ONE HDMI kit in this comparison. The big tradeoff is installation: it has to be soldered into the console, and the description says it's for advanced installers. If you're comfortable with that kind of work, this is a direct digital-to-digital HDMI route for the N64.
PS ONE HDMI Mod Kit
The Hispeedido PS ONE HDMI Mod Kit is a digital-to-digital HDMI upgrade for PS ONE consoles. It supports 480P and 1080P output and includes an OSD menu, three video modes, six aspect-ratio options, and adjustable deinterlacing. At $51.50, it has the highest listed price in this group. The kit is console-specific, but installation needs good welding skills and the listing says no paper manual is included-you can request the manual after receiving the product. It's a dedicated HDMI path for anyone committed to modding a PS ONE.
Universal Type-C Power Supply Kit
This Universal Type-C Power Supply Kit replaces the original power supply for a wide range of classic systems, including Nintendo NES, SNES, Sega Genesis, Mega Drive, and original PlayStation consoles. It comes with a USB Type-C cable and a 30W AC adapter, and the listing says installation is plug-in with no soldering. At $44.99, it's priced between the two HDMI kits. The limitation is that it handles power only-it won't give you HDMI video output. The listing does note compatibility with RetroGem HDMI boards and other mods, so it can be paired with a separate video upgrade.
Final recommendation
Use the decision matrix as a starting point. If you're building a GPi Case and want a display shell, the GPi Case Protector is the pick. If you own an N64 and have soldering experience, the N64 HDMI Mod Kit gives you HDMI at a lower listed price than the PS ONE kit. If your target console is PS ONE, the Hispeedido kit is the dedicated solution. And if you just want to unplug those old power bricks and use one USB-C cable across several consoles, the Universal Type-C Power Supply Kit is the no-solder route.
