After seeing the New Super Mario Bros Wii I realised how much I've missed a 2D Mario platformer on a home console, so I decided to check out some of the many many hacks that are out there via my Wii's wonderful SNES emulation.

But, seeing how there are hundreds of these at various degrees of quality/completion, I am very keen to hear people's recommendations and feedback on some of these. Where's a good place to start?

Your input is much appreciated.
