Meh. I got one of those packages before. It will be an "HK" (one made by DT), so the native Neogeo emulator will be useless. But beside that it's fine.
As for the accessories: That bag is crap and is likely to tear soon. Silicone glove is useless and awkward. And cheap arse no name SD cards is a bad idea. Don't be surprised if the card starts bugging out or quits working altogether a short while down the road.
