Pieces of it are grey and ugly looking and its starting to chip. It looks fine from the top though haha. Anybody know where I could get a replacement ems 64 shell?

I used a DPDT switch because I used the inverter made by Justin Thursday featured on Kitsch's site.
If you wanted to use a SPST switch then your going to need a 74HC86. More info on the 74HC86 here: http://blog.gg8.se/wordpress/2009/11/23 … d-palette/

I don't have any solid info on DPDT + 74HC04. I pretty sure its possible in theory, I'm no switch expert tough so I'd either recommend looking into the 74HC86 or purchasing the switchable inverter board: http://store.kitsch-bent.com/product/hex-switch-v1

Hi,

One question, why do I need a DPDT switch to change the inversion when using a 74HC04 ic?, Why would not a SPST switch do the job?

Do you have a link or something I can use as a reference in order to understand how to connect the DPDT switch to the 74HC04 ic, basically I need to know how the connection goes?

Thanks

This is the exact switch I used.

Thanks for all the photo's and information!

I honestly just went to radioshack and pulled out the switch drawers till I found the smallest dpdt silver bat switch I could find.

I'd take a picture of the switch in place but I'm kinda not opening this dmg until I get a part for it.

GoingHam, have a part# you're willing to share?

i'm just guessing thats part of the issue because a square/rectangular-bottom part is probably not placed with the bottom oriented diagonally, which leaves two ways it could be placed (just a 90 degree turn).  it would just matter which way you want the switch to flip, left-right or up-down.

a round-bottom part could be turned however you want, just depending on the way you want the switch to flip.

Could you make a picture of the DPDT switch inside the Gameboy and how that is situated please?
I'm having trouble getting mine in.

Haven't ordered anything yet, just making the holes already wink

Thanks in advance!

I'll usethis for sure and if I run into any troubles, you'll here from me again (:

Thanks again!

Cut your PCB accordingly as the red lines and my example show to allow room for the jacks and the dpdt switch. Don't cut off any little electric doo-dads, just the board.

Cut out the plastic leg thing outlined in red, try to make it as flush as possible with the inside walls of the casing. Just use an x-acto knife. This is where your switch will go. Also, the switch should be placed in so it flips horizontally otherwise the shell won't fit together like it use too.

Now as for the inverter board, I recommend placing the inverter board directly below the volume potentiometer, there is plenty of room in the highlighted area.

In the end you should get something that looks shockingly similar to this.

The power switch is directly behind it where it normally is. I didn't have to modify the power switch, just removed one of the three plastic legs in the face half of the shell. Its kinda hard to explain but I could take a picture of it if you want.

Btw: where is your powerswitch? Or did you switch the plastic switch to a DPDT?

Your going to need to modify the casing by putting in the holes and removing the plastic power switch holder closest to the edge of the casing.
Also your going to need to cut up your front PCB, Be CAREFUL!
