MAME4All

Hi Guys,
There is a free game in the App Store called Gridlee.
It's probably legitimate in that they have permission to run the
ROM images from the game, but it uses the current MAME4iOS
to run it, and the author included a side loader for external ROMS.

I'm sure it will get pulled when Apple find out, but until then you
can get a signed MAME for non-jailbroken devices.
Cheers, Art.

Well it works....

Once you load your own ROMs the normal game goes away,
and the App loads straight to the ROM selector menu.

I think this was just a way to get MAME signed.

If your device is jailbroken you just go to Cydia and download MAME4iOS.
