Hi all , first post so firstly Hi and hope someone can help me . I acquired a cocktail game system a few months back and it all worked well with gameex auto loading and then firing up the roms. Turned on today and it is stuck at the loading screen ,I have no clue how to go about resolving this . Have left it running for a few hours however nothing …. Saw something about turning off the verify Roms option but how and where do I this ? Really really appreciate any help . Thank you !
