Sept 3rd. Update: Added inside pictures as requested. Feel free to get in touch if you need further information. Have fun! I've just completed my PIGRRL 2 with a larger LCD, 3.5 inches from "Tontec," and a larger battery set at 3200mAh. Thanks to Adafruit and excellent documentation, along with some great web sites with key tweaks, I was able to make it work. Notes: As I used a different LCD (TONTEC 3.5), I had to do some tweaks to work with the original image supplied: Install the LCD driver (http://www.itontec.com/download/); Had to change the flatcable pinouts to other available pinouts because my LCD uses some of the PIGRRL 2 required GPIO pins; Changing the flatcable pinouts requires also changing the pinout mapping on Adafruit's "retrogame" application (https://github.com/adafruit/Adafruit-Retrogame); Had some issues with the LCD to show up Retropie on the screen, so I installed "raspi2fb," a software that copies the image to a secondary framebuffer (https://github.com/AndrewFromMelbourne/raspi2fb#raspian-wheezy). Finally had to learn how to use Autodesk Fusion 360 in order to adjust the screen size. Below some tweaks in order to properly compile and install retrogame on Jessie: sudo apt-get install libncurses5-dev libncursesw5-dev unzip make CFLAGS=-DCUPCADE sudo make install sudo modprobe uinput sudo retrogame sudo nano /etc/udev/rules.d/10-retrogame.rules SUBSYSTEM=="input", ATTRS{name}=="retrogame", ENV{ID_INPUT_KEYBOARD}="1" sudo nano /etc/rc.local /usr/local/bin/retrogame & And the mapping I decided to use (retrogame.c): { 27, KEY_LEFT }, // Joystick (4 pins) { 19, KEY_RIGHT }, { 16, KEY_UP }, { 26, KEY_DOWN }, { 23, KEY_LEFTCTRL }, // A/Fire/jump/primary/RED { 24, KEY_LEFTALT }, // B/Bomb/secondary/YELLOW { 20, KEY_Z }, // X/BLUE { 14, KEY_X }, // Y/GREEN { 5, KEY_SPACE }, // Select { 6, KEY_ENTER }, // Start { 12, KEY_A }, // L Shoulder { 13, KEY_S }, // R Shoulder Had a real blast doing this; I've already built two for my kids. My wife is now asking for a third one, maybe next will be five inches or seven inches
