All of Nintendo's consoles get a refresher this weekend, but at least two of them are something you might have played before. One is a retro classic, the other is popular iOS title.
3D Classics: Twinbee (Nintendo, $7.50) -- Nintendo's 3D Classics range expands with yet another vertical shooter, TwinBee. The 3D effect works great with these shooters and TwinBee is a great coin-op classic. It's also going to be a lot better than Urban Champion was.
Cut the Rope (Chillingo, 500 Points/$7.50) -- iOS favourite Cut the Rope finally arrives on DSiWare after a long wait since its announcement. If feeding a little green alien candy sounds good to you (and it should) then you should consider this. It is a bit more expensive than the iPhone version however. About $6 more in fact.
WiiWare 101-in-1 Explosive Megamix (Nordcurrent, 700pts) -- Remember those Game Boy cartridges that promised 101 games and then they all ended up be dodgy sprite replacements of Super Mario Bros? Yeah well this is nothing like that you filthy pirate, there's actually 101 games in here with a promise of 10 hours of gameplay.
