Play as the real Super Mario 64 Mario in Minecraft: his whole moveset, his sounds and the soundtrack, from your own ROM.
Press M in a single-player world and you're Mario, moving exactly as he does in Super Mario 64: triple jumps, long jumps, backflips, wall kicks, ground pounds, swimming. Minecraft's blocks become his world as you go (stairs are ramps, ice is slippery, lava gives the burn jump), you stomp and punch mobs, and the original soundtrack plays from your ROM, following where you are.
Controls: M turns you into Mario and back. H pins the controls card. A gamepad works too (Xbox layout).
Needs your own Super Mario 64 (USA) ROM and a Minecraft: Java account. Melty builds Mario (libsm64) on your PC the first time; nothing of Nintendo's is downloaded. Single-player.
