I had a perfectly working installation of PiPlay and I launched the update script, after installation the menu did not show up, instead a python error message was shown complaining about certain "keys" length, I checked the yaml config file that was cited in the error and I found weird text that seemed like an installation log more than a config file in the middle, I commented these lines and the GUI came up with no errors.
However, when I launch any NeoGeo rom, I get a "Segmentation fault" error. These games were running fine just before the update. Other emulators work fine (I only tested SNES and NES)
Do you have any ideas how to fix the "Segementation fault" or where to look for debug info?
That means that you made changes to the same bits of code that the update also changed. So it keeps both changes in the file but requires the user to make a choice between them (delete or comment out the other). I would double check your the neo geo section to make sure that everything is ok. You can also compare against the default config.yaml file HERE.
