Hi everybody i am a noob but have used several MAME frontends before, I have followed the youtube instructions and imported my roms and downloaded mame0217b_64bit.exe which Whenever i try to play a game and doubleclick, 7-zip comes up and wants to extract the mame0217b_64bit.exe, if i let it do it, it says it can not overwrite the .Exe file Obviously i am doing something wrong but what? - i have unzipped the game roms in a separate folder, but all my roms works fine as zips with my other MAME frontends. Kind regards Daniel
