You have to download ROM files and put them in the ROMs folder. Download from www.mame.dk and do not unzip them, just copy zips to roms folder.

> I've installed the Extra Large Build (made the folders \MameCE and \MameCE\ROMS,
> and copied the 5MB exe-file to \MameCE, the GX.dll was installed already).
>
> When I start the exe-file I get a blank screen with a 'Play' and a an 'Exit'
> button in the lower part of the screen. If I choose Options-> Show All Games I
> get a huge list of games, but whenever I try to start a game the screen goes
> black for a second and I'm returned to the game list. I've tried dozens of
> games, and the same thing happens every time. I have no other programs running
> (except the File Explorer), I have 15 MB allocated to programs, of which 12 MB
> is free. I have tried soft resetting the device.

> Any help would be appreciated!
