Most interesting among the multifarious offerings: a few forgotten Konami MSX games on VC, and 530 Eco Shooter on WiiWare. That's ... an Intelligent Systems-developed shooting game about shooting cans. The cans are alive and move around. It's weird. Also weird: Nintendo's Neratte Spot! for DSiWare, which is about throwing bombs into the mouths of fish.
The whole list is after the break, because it's crazy long.
