not a retro port as such but the gameplay is quite retro[ish]: MINISQUADRON great fun addictive little game
its been to many years since iv played it on nes.. so I honestly cant say if i think its better or not.. but i think if you enjoyed it on the nes.. you will probably like this. also there is a 15,00 itunes gift card if you beat the game/goals offerd by the developer of the game. here is the thread. http://forums.toucharcade.com/showthread.php?t=39568
Another to add: Karate Fighter is a fairly faithful (unofficial) port of Irem's classic 1984 arcade game, Kung Fu Master, complete with extra levels and bosses. Some folk have had troubles adopting to the touch controls, so anyone interested in trying it should definitely try the 'lite' version first to avoid getting burned.
There's a Lode Runner-like game called Gnome's Treasure. With the new control scheme, it is very good!
