Hello when i dwnloaded the firmware and copied it to sd card there was no moonshl file, although it worked to put games on but I have a 2gb sd card, I put games on the sd card and only a handful of them showed up on the ds when swiched on, about half of them. Not sure if one thing has anything to do with the other?
the moonshell for acekard is here http://www.acekard.com/download/ak2/moonshell.zip make sure your games are fully extracted, the games have a .nds format.
