"It probably won't break anything" ! Make a complete backup of your current image is the best idea.. and give it a go. In theory nothing should break, there are no special drivers or anything special compiled in. The battery icon is a background service, the only exception is that the autostart scri...

Ah mystery solved! I typically "hold" the button when assigning hotkey to skip it, and it defaults it to SELECT anyway. There was a time when doing that would disable the select button, I have a feel that is fixed but I still always skip setting it and it defaults to SELECT.

Never seen that before, if you use a USB gamepad or something does that do the same? Have you tried other software? Does holding the button down (rather than just pressing) make it better or not?

Check the USB wire soldering (the 3pin JST wire) and check for shorted between the soldered contacts, post pictures of that area if you'd like my feedback on it

Hey, currently there isn't a way to adjust it, i'll add it to my todo list and see if I can make it do it by itself. If you ever use HDMI out you'll also see the same pattern of it being much smaller!

When run in tester mode, does the USB AUDIO test pass?

Just curious -- what was the resolution to this? Should we use 6400000 for the 640x480 screen as well? The 640x480 requires at least >18432000 (that's 18MHz, the 6400000 is 6.4MHz) but will likely be higher because 18MHz doesn't take in to account any blanking lines. You could try the following and...

That sounds pretty awful! Have you tried other sound producing things? Could you also collect the log file https://github.com/kiteretro/Circuit-Sw ... -log-files and zip them and send (email is fine) and I can see if there's anything obvious there

Use the image from https://github.com/kiteretro/Super-AIO/releases for the Zero, and then after you have written the image edit the config-saio.txt file on the 56MB partition that appears when you insert the SD into a PC, and change the commented out line to be the TESTER one

Yeah all are the same signal, and that all sounds perfect! Right, i'm 99% sure then that the LCD you have is at fault. The backlight IC and circuit is working correctly, but it's like the LEDs are dead in the screen! As a last thing, can you inspect the LCD connector on the board, check there is no ...
