SYF Mainboard 315-5535 / 315-5682 v2.0 for SEGA GameGear
This is a brand-new manufactured replacement mainboard compatible with your Sega Game Gear, using all new components. This board makes it possible to repair your VA1 / VA4 / VA5 / Majesco model Game Gear which suffers from PCB damage caused by leaking capacitors or batteries.

SYF Mainboard 315-5378 v2.0 for SEGA GameGear
This is a brand-new manufactured replacement mainboard compatible with your Sega Game Gear, using all new components. This board makes it possible to repair your VA0 model Game Gear which suffers from PCB damage caused by leaking capacitors or batteries.
 
The board has been reverse engineered from a Sega Game Gear. Since I am not able to source new ASIC chips, cartridge connectors and expansion port connections, you need to supply these parts from one of your broken boards. TV-tuner is not supported - this is limited due to the current available LCD kits.

Installation is done at your own risk. I do not take responsibility for damage resulting from installation. Experienced soldering skill is needed – do no buy this kit if you do not know how to solder fine pitch SMD chips.

Manual and more information can be found here: Game Gear Mainboard 315-5378 – SYF

Not quite "indestructible"
Color: Green+Brown
These toys are so cute! But, they are NOT for aggressive chewers! 15 minutes and they were ruined. But for kinder chewers...they are adorable.

Easily Destructed
Color: Green+Orange
My dog destroyed it within a couple of days. The “rope” turned into strings which is dangerous if eaten

Great for Small to Medium Dogs
Size: Critter Zoo, Color: 5 Different Animals
I bought these for my boys to play with. One of them loves to tear the squeaker out of anything that, well, squeaks. These do more than squeak! So far, they have survived the terrorist chihuahua/piranha boy! They’re pretty awesome toys and my kids’ favorites! They’re sturdy and goofy looking! I’m writing this review a couple months after my purchase. One reason why is I want to “buy again” (just because they have their squeakers, doesn’t mean they haven’t been chewed on!). I have a large, long chihuahua (<—— terrorist/piranha boy) and a min-pin mix. These toys are the perfect size for them. There is some chew damage from the terrorist but considering he can get a squeaker or of a Lamb Chop within 5 minutes, I’d say these toys are the best I’ve run across in quality, thickness of the material, minimal stuffing and durability. Highly, strongly, encourage you to, purchase if you’re looking for good toys for small to medium dogs!
