Gameboy Mods

Stores

Aliexpress
- hard to find the right items, but the items are cheaper.
Retro Game Repair Shop (RGRS)
- A reseller site, but decent experiences so far.
Funny Playing
- Decent for more costly parts, but they also focus more on their first party products
Handheld Legends
- Has the largest selection (though it doesn't overlap that much with RGRS), and is probably the goto for customization, but hard to navigate

Basic Build
- This is really just replacing the screen with a new backlit one. Everything else is the same, plus or minus replacement parts to fix anything broken.
- Cost ~$90
  - GBC ~$50: assuming getting a broken one and fixing it.
  - 2.4" Replacement Screen ~$40: A fairly basic backlit screen that fits into the original shell. It's slightly smaller than the OEM screen, but not by much.
Fancy build
- This is a more involved build: a bigger screen with more features and a rechargable battery
- Cost ~$150
- GBC ~$50: assuming getting a broken one and fixing it.
- Power Mod ~$45: This is a new power circuit for a rechargable battery. Required for the larger screen.
- 2.6" IPS Screen Kit ~$55: Kit comes with the screen and a shell. Original shells can be modified for the 2.6" screen, but it really isn't worth it, just buy a new matching shell.
Extra Costs: Doing any more involved customization as far as colors and such will start adding costs in materials, as will more replacement parts.

Capacitors and fuses
- like $5 for a whole set from any of the stores if you need to replace them
- best to bundle in with a larger order to not get hit with shipping
Battery Cover
