After make the 31 update, a lot of cores is missing (for example: i had 5 mame cores and now i have only 2). All custom setup core per games was lost too. All is now set to “Automatic” and this made some games not working. I cant download more cores too. The menu display of this option was disable. I,ve set to enable again but when i enter in this option, nothing happens… (the screen with cores to downaload is not showed) :(
