is there a list of games and ratings?
From the amazon review here [amazon.com]
I got one of the very first iCades when it was released and back then, the Atari app was the only compatible one. There are a lot more now. Also, since the third generation iPad isn't shaped all that differently from the iPad 2, it's most likely compatible.
The Atari app is OK since you can download all the games for $9.99 (not a bad investment.) I've mainly been playing games through the iMAME4all app (available in the Cydia store for jailbroken devises). The iMAME4all app supports around 2000 classic arcade ROMS like Metal Slug, 1941, Gauntlet, Mortal Kombat, Teenage Mutant Ninja Turtles, Galaga, etc. That alone makes it well worth the price.
I've also used it with a Super Nintendo emulator and played games like Super Mario World, Super Castlevania 4, Mega Man 7, etc. I'm sure it will work with other emulators too, but these are the only two I've used thus far.
There are also several standard App Store apps that are now compatible:
Compression HD [Free]
Emerald Mine [Free]
IronStar Arena [$.99 / Lite]
Minotaur Rescue [$.99]
Minotron: 2112 [$1.99]
Mos Speedrun [$1.99 / Lite]
No Gravity [$4.99]
Plum Crazy [$.99]
Sideways Racing [$.99]
Silverfish MAX [$2.99]
Space Inversion [Free]
Space Inversion Puzzle [Free]
Super Mega Worm [$.99]
Super Mega Worm Vs. Santa [Free]
Super Drill Panic [Free]
Velocispider [$.99 / Lite]
Warblade HD [$2.99]
Looks pretty slick to me. Thanks OP!
