Hi Mach_5, I built as instructed and my function buttons were assigned as stated. The a, b, select and start work in emulationstation, but once I get into the game, (tried snes super ghouls and ghosts) the function buttons don't work. Can't even get out using vulcan nerve pinch and have to reboot from putty. I checked the retrogame.c script and the gpios are assigned to the correct buttons, and check my button connections to proper pins and ground, so I am thinking it is a config issue. Any thoughts? Thanks.
Thanks! Also, I used the same TFT you used with same settings in config file. However the screen flickers. You have 240 x 320 with speed at 80000000 and refresh rate at 60. Tried tweaking these to no avail. Did you have this problem?
Hi I built your project but decided to add sound. Since the zero board does not have PWM0 and PWM1, Lada Ada posted a nice tutorial on using GPIO wiring tool to change pin assignments. She recommended GPIO 13 (PWM0) and GPIO 18 (PWM1). However, your instructable uses GPIO 18 for the down button on the D pad. Is there any way to use another input for this to free up GPIO 18? Thanks.
It appears from the pictures that the TFT does not line up with the case opening properly. Was this just a design error? Thanks
Are any game roms included in retropi download? If not, what is a good source of roms compatible with retropi? Thanks.
Thanks. I realized that the pi zero does not have an audio output jack like the pi B, and the output needs to be configured to different pins as the zero is smaller. Also, a filter needs to be built to output sound in the audible frequency range. I am going to try a usb sound dongle as that might be easier to get sound.
Hi Can you output audio directly from the board to a mini speaker or do you need an amp circuit?
