Okay, so purged and re installed everything and now seems to be working again, but now the gui is different, reverted back to the setup with the small icons, which i believe disappeared last time after installing the custom config, being replaced with a gui with larger buttons.. Also still seems to be giving me more sigsev errors than before, sometimes i will get an error but the game will still run, although i won't be able to close the window unless i press the power button and then 'end current task'. Trying to run mupen again will give me a constant stream of sigsev errors which makes the phone unresponsive, i have to repeatedly press the power buttonand eventually i'll get the option to end current task..
