Ratings and reviews

It doesn't work properly at the moment. The saves backup works but the games back up just says "Completed successfully" immediately without backing up anything. It'll be cool if it could back up to other services besides Dropbox. People that use emulators are often tech savvy, so an option to backup to personal clouds would be really cool. Even if it is through something basic like SFTP.

it says to link with dropbox account and when i press it it loads in chrome and i log in to dropbox account and it asks permission and i press allow every time the same permission asking allow screen appears and this happened till 9 tabs then i gave up. please try to fix the issue Edit: it works perfectly in my new phone but not in old phone idk why🙃

im so sad i installed and connected everything to the folder where i keep my game, but as soon as i went back to the john gbac emulator app the files couldnt be opened. then when i unlinked my account to see if that would fix the issue, all my save data was deleted. please help!! this is my favourite emulator system but i cant keep losing my data over these issues 😢
