Fixing a retro handheld can mean two completely different shopping carts. You might need a tool that opens the shell, or you might need a part that actually restores power. In the gaming replacement parts modding space, the For Nintendo Switch N64 NES Game Boy Switch Triwing Screwdriver Repair Tool Kit and the Power Switch Part Board Replacement Game Boy/Pocket/Color/Advance/GBA/SP/GBC/GBP land on opposite sides of that split. Pick the wrong one and you'll have a screwdriver set when you needed a switch board, or a switch board when you needed to get inside the case.
Quick Verdict
If your immediate problem is a console or controller that won't open, the $6.63 Triwing Screwdriver Repair Tool Kit is the practical choice. It includes a 10-in-1 screwdriver set, covers Nintendo Switch, 3DS, 64, DS, Game Boy, Game Boy Advance, and Game Boy Color, and is meant for both consoles and controllers. If your Game Boy needs a new on/off switch, the $8.99 Power Switch Part Board Replacement is the actual component you need. It comes as a 5-piece set for the Game Boy family, so you get spares for multiple handhelds.
Comparison
| Product | Listed price | Best for |

Where Each Product Wins
Choose the Triwing Screwdriver Kit when you need one tool to handle multiple consoles and controllers. It's the broader toolkit for a full teardown session.

Product Notes
For Nintendo Switch N64 NES Game Boy Switch Triwing Screwdriver Repair Tool Kit

Autopartsshop's kit is a solid first purchase for anyone starting to mod or repair Nintendo hardware. The 10-in-1 set includes the triwing bits that Nintendo handhelds and the Switch are known for, and the compatibility list is wide: 3DS, 64, DS, Game Boy, Game Boy Advance, Game Boy Color, and Switch. It's listed as new, works on consoles and controllers, and the color is simply 'as picture shows.' The obvious limitation is that a screwdriver kit cannot replace a broken component. You'll still need a separate replacement part, like a power switch board, if the goal is to fix a specific failure rather than just open the device.
Power Switch Part Board Replacement Game Boy/Pocket/Color/Advance/GBA/SP/GBC/GBP

This is the part you buy when the diagnosis is clear. It's a power on/off switch replacement for the Game Boy family, specifically matching Game Boy Advance, Game Boy Color, Game Boy Pocket, and Game Boy Advance SP. The set includes five pieces, so after you fix one handheld you have spares for another. It's a new part, and it's aimed at consoles and handheld consoles within the Game Boy line rather than Switch or N64. The main limitation is the narrow scope: it won't open the case or fix unrelated faults. It's a targeted component for a targeted symptom, which is exactly why you should pick it only when the power switch is the known culprit.
Final Choice by Use Case
If you're buying for general gaming replacement parts modding, start with the Triwing Screwdriver Repair Tool Kit. It gives you the access you need for almost any Nintendo teardown. If your Game Boy's power switch is the reason it's not working, go straight for the Power Switch Part Board Replacement-it's the fix, not the prep. When both jobs are on your bench, the two tools solve different steps of the same hobby, and you'll probably want each in your kit eventually.
