If the screen seems scratched in the photos, that's only because it still has the protective film on it.

The "Game Pie Advance" is a project we are working on to install a Raspberry Pi Zero inside of a Nintendo Game Boy Advance (GBA) shell. This auction is for one of the working models that we've created. We are selling this on eBay to gauge interest and raise funds to continue this project.

This is a fully working Linux computer running inside of a GBA shell. It is currently running the RetroPie Linux distribution on an included 16GB MicroSD card. Please see https://retropie.org.uk/ for more information about RetroPie. You can plug in a USB hub with a keyboard, mouse, network adapter, etc. You can also plug in a HDMI monitor to this and play on a larger screen.

I believe that, even though this unit is fully functional, the best candidate as a buyer for this auction would be someone familiar with Linux or RetroPie. It is fairly simple and intuitive to add games and features to this system, but this is not yet at the level of an off-the-shelf game console. If that is what you are looking for, I suggest getting yourself an actual Game Boy Advance. :) Basically, what I'm saying here, is "Please expect to tinker with this." If you're not comfortable tinkering with Linux or Raspberry Pi machines, then this may not be for you. However, if you still just want to financially support this project and have a fun time playing some games, then maybe this machine is perfect for you!

I am setting a "Buy It Now" price of $299, because the first GPA unit sold for $302 on a 10-day auction (http://www.ebay.com/itm/322231541500). I will also consider offers, so please make any offer you feel is fair.

This unit runs off of USB power or batteries. If you want to run this machine from batteries, it requires 2 14500 batteries. IT DOES NOT USE AA BATTERIES! The 14500 batteries are lithium rechargeables that are the same size as AA. I plan to include 4 14500 batteries plus a charger with this sale.

Please see these videos of a couple different Game Pie Advance units in action:

As an engineer, I feel the need to discuss potential deficiencies. I don't want any bidder to be surprised, so here goes.

The MicroSD card on the Raspberry Pi Zero is in a place that is not readily accessible.

To remove the SD card, you must open the case. I will include a tri-wing screwdriver, so you can open the shell.
If you were so inclined, you could hook the MicroSD card up on an extension ribbon cable and place it in a more accessible location.

To boot the Game Pie Advance, you must hold the power "button" in the on position until the LED comes on. Then Linux will take over and you can let go.
While booting, the built-in screen is blank for quite a while. The HDMI has video immediately.
This does not have X and Y buttons. I did not want to modify the outside of the shell, so only the original GBA controls are present. There is a header to solder extra controls to if you wanted to add features like X/Y buttons.
The 14500 battery life is only about 1.5 hours in our testing.

When the batteries get low, the audio usually cuts out and then the system will just die.
You can usually plug in the Pi to a MicroUSB power source to keep it running.
Another option would be to use a USB power cell (like people use to charge their phone on the go) and just plug it into the Pi's MicroUSB socket.
If you are a modder/hacker type, you could easily mod this to use a different battery. One of our design decisions was to keep the AA battery compartment, so we chose batteries that fit inside of it.

Even though this uses 14500 batteries that are rechargeable, it does not charge them. You may want extra batteries or to just run this from a USB power source.
There is some diagonal tearing on the screen at times. This is most apparent when a menu or game fades in/out.
