This step is for pure Lolz. Adding the game music has a few detriments to it but overall adds to the epicness of this wallet.

Detriments are: less space for cards and or batteries, harder to close if positioned wrong, takes more time to complete wallet, can't be turned off for quiet areas like libraries and schools without using tape to temporarily disrupt the connection.
Benefits are: Epic sounds when opening wallet, laughs and awe, the admiration of your gaming community.

The hardest part of this is getting it to turn off when closing. I almost gave up on this section for that reason alone.

PROCEED!

Purchase your game greeting card (with sound) of choice or recycle one that a relative gave you. I bought a game related card to better tie in with the wallet. (Go Dig Dug)

(Note, I've noticed freakin huge greeting cards as of late, do not get these! The sound card may be of different dimensions, that speaker inside sure is... Get the normal sized sound greeting card.)

Peel open the greeting card to get at the circuitry. Peel it away from it's double sided foam tape shackles.

Use your wire snips (dremel is a tad un-needed) to sever the top battery shell away and remove the battery, but keep the metal tab that completes the connection.

(keep the battery for a throwie!)

Use a soldering iron to melt the solder of the wires connecting the speaker to the card. (You can use a desoldering iron if you wish, but I didn't see a need.)

On the faceplate half, right side, dremel away the same vertical walls that originally stacked on top of the walls where the batteries now are.
Use double sided tape and place the card in the top right corner of the faceplate but give it a millimeter or two of a gap on the side that the hinge is on. This gap is so the battery terminals have somewhere to be and don't butt up against the card itself. (It's the top right if it were closed, if you have it open with the backplate on the ground, it's the bottom right. if you have the faceplate on the ground with the inside of the backplate in the air... then I mean your top left. If I've confused you look at the pictures.)
Close the contraption. If it's not closing all that well, you might need to dremel out a little scoup for your capacitor (that little black cylinder that hangs off) to lay in so it's flat. Also check if your wires are getting in the way. If it still does not lie flat completely, it's not the end of the world, as long as it closes most of the way you'll be fine.

Take your piezo speaker and if you wish, dremel or wire snip away one or two sides so that it resembles a rectangle with two rounded sides. This will not harm the speaker in any way, just do not dremel too close to the center section of the speaker, it is very breakable.

The reason why we don't use the speaker given with the greeting card is because it is simply too thick! This will take up the space that useful credit cards could fill! Also most speakers are made up of a magnet. The paper thin piezo speaker that we use does as well but it is very weak. Using a bigger speaker could tamper with the credit card magnetic strips! Oh noes!

Place your piezo speaker below (above if it's opened with the backplate on the ground) and then tape it in place. Solder the wires to the previous speaker's connection points. If you lost track just test them by touching the respective 6 inch wires from the batteries to the negative and positive positions on the card where the battery was then touching the speaker ends to the points where the last speaker was. if it doesn't work, you either got the speaker ends wrong, or the power connections wrong. DON'T leave your batteries connected while soldering!

After you have it soldered untape your speaker. Now ask yourself, how much sound are you going to hear out of this? Well if you tested it, you know the answer, not much. But it's still loud enough to be annoying in a quiet environment. But if you want to hear your speaker a little better get a 1/16 drill bit and put it in your dremel. If you observe there are two lines on the outside of the cartridge that overlap the section where the speaker sits! Line up your drill bit with these holes and dremel three evenly spaced holes in each line that overlaps the speaker. Now you can hear it just a tad better! Annoy those church ladies as you make your contribution! Entertain the cashier as you pay for those ingredients for the waffles you are about to consume.

Now for soldering your battery connections. (Be sure your batteries are out!) I said 6 inches before to give you a little to work with. Run your 6 inch wires up between and below the batteries then under the negative spring. Check how much extra it will take to complete the connection then snip off the extra and strip the wires. Twist the wires and solder. Make sure you don't have so much wire that it gets pinched buy the opening and closing of the wallet.

Take off that double sided tape and Gorilla super glue the card in the position it was in before then put some regular or electrical tape over it except where the clamp is.

Tape up your batteries in one layer of tape each. Put superglue over the place where the wires are at then lay them down firm and stick in the taped up batteries. Sticking them in like this will shift the wires where they need to be and prevent the glue from keeping your batteries in place forever.

FOREVER!

Well by now you've realized your music works. Good job you.

Now the hardest part of the instructable (at least for me). Turning your sound OFF when you close it.!

If you added the fabric like I did, you're going to eventually realize that it is in the way, like I did. So take out the portion of fabric that is below and around where the positive clamp is on your card.

If you haven't finished that Pepsi do it NAOW!

Clean out your bottle and take off the label, cone, and base with your exacto blade. Slit a straight line down the middle of the cylinder you have left. Cut off about a 2 inch square so you have something easier to work with. (Once again, the section under the label should be flat.)

With this square we're going to cut it down to make a tab that will slip under the metal positive connector to disrupt the connection and cut the sound whenever it is closed. So as far as wideness As far as wideness goes it needs to be no wider than the width of the metal section that the metal positive clamp hits to complete the connection. Make a tab and bend around 2 millimeters of it into the curve. (so that if it were still connected to the bottle, the tab would be inside the bottle. Glue this little tab to the space below the sound card (be doubly sure to roughen it up first) with the edge of the tab against the inner cartridge edge (look at the picture for clarity). Now it's longer than it needs to be of course, but you can always cut it shorter, which is exactly what you'll do. Cut it just enough so that it fits under the raised portion of the metal clamp but doesn't raise it any when fully opened. If it helps, do what I did and bend the end just enough so that it contours to the raised portion of the metal clamp.

If your clamp is having a hard time staying connected, take one of the bits you have for your dremel or a 3/32 drill bit precisely, and place it right below the part of the clamp that's bent and well, just push it down to give it more bend.

You will most likely have to play with this setup for a while.

Also, a note. After opening and closing this wallet for a while in normal use, the metal clamp still comes unbent, even after using the method mentioned above, because it's so weak. So my only suggestion to remedy this is superglue a small bit of rubber band over the metal clamp so that it always is pushed down by the rubber band.
