Re: retrogame.cfg problem

Use the BCM/gpio number not the physical pin number. For 'A' use 16, not 36. Do the same for the rest...it will work. Retrogame NEEDS the BCM/gpio number not the physical location number.

Re: Megabat battery

Not all Chinese sellers take forever. If using AliExpress make sure to choose Ali express standard shipping or epacket. It's usually decent speeds.

You could also consider the dextech battery too.

Re: Megabat battery

Re: Screen and Audio Help

yeah, you can wire the usb sound card directly to the volume wheel, headphone jack, and speaker. If it's too quiet for your taste you might want to add an amp. But it is not 100% necessary. I have done lots of builds with only USB sound cards. As for the chips you listed some information. Which is g...

Re: Screen and Audio Help

As for the screen, you need to post clear pics of the black 8 legged chips. So people can see the numbers. Or you can just look at the numbers on them and google search to find info on the chips and see if one of them have a 5v pin. If so solder a jumper to that. Also, if you have a 12V power source...

Re: Screen and Audio Help

Your audio will be something like this: http://i.imgur.com/YTlQdlX.png Look at the bottom of the USB sound card too, if it's like the one I have at home (looks to be) it will have labelled pads, L out, and R out.

Re: Full VGA resolution (640x480) 3.5" display, composite in

yeah, strange. You might just have got some bad luck and have a non working screen. Not much else I can do to help.

Have you tried CVBS2 instead of the CVBS1?

Re: Full VGA resolution (640x480) 3.5" display, composite in

Hi thanks for your answer! Nope we could not test the screen before. The 3,3 V are to the button board of the screen. 5V are on the VGA Board as shown on the board (attachment). What do you mean with test pad? The Image on Raspi works (tested with hdmi). Also inserted display_mode=3 for testing in ...
