It's not a prototype... It's the red anniversary wii's donkey kong original edition that came pre-installed for us in europe. The wad isn't on VC, so a nand dump had to be made. I managed to get the wad from some french site, and with collobration with thefox we got this released *brag*. Because, you know, all nes game wad's have a actual nes rom in them. Some can just be hex edited out easy from one of the files that's unpacked from the wad, but this one and more recent ones needs to be decompressed first with a lz77 decompressor (especially made for nintendo wad's, they use a modified version of lz77).
It's really cool nintendo did some assembly in 2010
Hope we will see more stuff like this, but we probably won't ^^
