I start by flipping over the device.

I remove 5 Phillips head screws for the case

And one more to remove the batteries

Inside, all I see are glorious Phillips Head screws!

Finally! Something repairable!

Battery Compartment

Power Switch and LED board

Mainboard/Joystick board

A and B button board

I start with the buttons.

They were very, very easy to get to and remove.

Now, for the mainboard.

2 screws get me underneath.

But, what's this?

Another 4 screws, and POP! it is holding a spring down, for the joystick.

There did not appear to be an easy way to get the joystick out, however.

Finally, I see a power regulator?

Nope! It's just the power switch and LED.

Back Main PCB IC Identification:

In conclusion, I LOVE how it's all the J1 Phillips Head screw, throughout the entire device.

It's easy to get under every board.

There are, unfortunately, no plugs, and so everything is soldered on. This removes the possibility of replacing any electrical internals.
