I'm having similar problems with other systems.
Before opening a topic, better trying to erase all the ini files,then.
Anyway, despite I've got the updated software lists and the corresponding xml files in the hash directory, I'm not able to launch any software of any system from the "software" window (it says it doesn't find the roms) and have to pick the roms directly from the "picker" window (sometimes works, sometimes not). Any clue for that? Thanks.
