I ran out of space on my SD card and have since cleaned some out - trash not showing any files BTW - but found the trashed files be snooping about the file structure
since then though retroarch no longer loads any games for any system - I checked in the logs and all it mentions is:
(emulatorlaucher:580) ,module. Exiting configgen with status -1
There are no other errors logged
Has anyone else come across this and can offer a solution please?
