I just signed up to let you all know that I am amazed at what you folks have accomplished here, doing "what Nintendon't" with the missing retro tracks and the new ones you have created.
I am particularly interested in GCN tracks.
My favorite conversions so far are:
Baby Park (MRbuttCHINSxMKWii),
Luigi Circuit (Torran)
Mushroom Bridge (Torran)
Sherbet Land (Tock)
Mushroom City (Torran)
Wario Colosseum (MKDasher)
Bowser Castle (Baoulettes)
Without the intention of disrespecting other contributors, I think these tracks posses a level of texture detail and overall quality that puts them on par with Nintendo's own retro tracks. I'm definitely interested in what Torran will work on next, as his ports are of an amazing quality.
My ultimate wish is that we get to the point where all GCN tracks will be ported with that level of quality and included in a Wii/GCN distribution (conveniently, there are 16 tracks in MKDD and 16 retro track slots in MKW).
Lastly, a big "thank you" to Tock for making all this happen, keeping everything together, the excellent wiki, and Wimm for producing his awesome distributions and that the tools that enable the creation of the tracks.
I'll look into your community events, as I would love to participate.
