The Porta Pi Arcade runs on RetroPie with Retrogame and some altered config files best for the Porta Pi Arcade. This gives it the function and feel of a true mini arcade. The biggest change from the raw Retropie image is Retrogame which enables the GPIO's to accept inputs and the RPi see's them as keyboard inputs. Retrogame is coded by Adafruit.
The versions below have been renamed to reflect the version releases of Retropie. All these images have Retrogame+Retropie in a turn-key setup meant for GPIO arcade setups, like the Porta Pi Arcade.
RetroPie and Retrogame credit goes to their respective authors and contributors, not me.

READ ME FIRST:
Is this your Pi with 26 GPIOs?
If you are using these images on a RPi 1 model B (shown on the left) and not a Pi 1 B+ , PiZero, Pi 2 or Pi 3 you must remove the extra GPIO lines (player two controls) in the retrogame.c file and recompile. Again, if your raspberry pi has only 26 GPIOs, you need to go here to see how that's done.
If you're raspberry Pi has 40 GPIOs all is good.
I reccomend using a Pi 3.
And remember: I, nor Retro Built Games provides any warrenty or guarantee for this software. Use at your own risk.
Troubleshooting: If you have issues with an image please consult the help sections to attempt a solution. Emailing me with "___ does't work" won't warrent a reply. I'd love to help everyone, but I cannot.

For Windows Users:
You will need Win32DiskImager to mount the image. You should download it.
Use an 8GB SD card or larger. Some 4GB SD cards will work (SanDisk, but some brands have slightly smaller amount of sectors making their 4GB just a tiny bit smaller (Kingston for example) than my 4GB image. My image was made on a 4GB Sandisk btw.
If you're using an SD that was previously used for something else (it's not fresh out of the package) I HIGHLY reccomend formatting it before mounting the image. When I say format, I mean more than just the Quick Format untility in Windows. You need to overrwite each sector to clear out any residiual data. This also helps fix issues when re-installing/ overwriting Raspberry Pi images on top of eachother- in case one image becomes corrupted or unstable and you install the same vanilla image (reformat for best results).
If using a brand-new SD card, skip these two steps.
A) Download/install SD Formatter tool.
B) Format using the Options: FULL=Overwrite and ADJUST SIZE = ON
Depending on the size and class of the SD card (class 4=slow, class 10=fast), the format may take 5-20+ minutes. When the format is complete, open Win32 Disk Imager.
1) Select the image (Porta Piv2.1 in this case) you want to write to the SD card. (if you downloaded the image unzip it first).
2) Select the device/ drive letter, (this is the USB SD card reader with SD card plugged in). Make absolutely sure this the correct drive letter. If you have an external HDD plugged in and select it accidently, all its data will be forever lost if you continue.
3) Click "Write". Unplug the device when it's complete ( it will take some time- enough time to make a sandwich). You now have a bootable SD card for your Raspberry Pi!
