Heres the release news

After about 4 months my childhood dream has finally come true and is available for everyone to enjoy.
For those of you who haven't seen my other videos: this mod replaces every character in GoldenEye 007 for the Nintendo 64 with Mario ones.

James Bond - Mario
Natayla Simonova - Peach
Alec Trevelyan - Luigi
Xenia Onnatop - Daisy
Arkady Ourumov - Bowser
Boris Grishenko - Yoshi
Dimitri Mishkin - Donkey Kong
Valentin Zukovsky - Wario
May Day - Pauline
Oddjob - Toad
Jaws - Waluigi
Baron Samedi - Rainbow Bowser, the Powered-Up version of Bowser from Super Mario 64.
Soldiers/Civilians/Scients - Koopa Troopas
Heads are now different expressions to make use of the Random Head system, hats/helmets are replaced with tiny models & Bounding Boxes of 0 because they would get hit first despite being inside the head. Thought about making them sunglasses, but it'd still get hit first before the back of the head did and overall was unfairly annoying.
Mishkin/Donkey Kong is no longer the Defense Minister, that role now goes to May Day/Pauline with Donkey Kong being the Head of Special Forces. This was done to give Pauline a role in the story, as well as explain why the "Great Guards" use DK's body.
Dr Doak is now Oddjob/Toad to give him some sort of role in the story, as a result the idea of Toad "blending in" with the other scientists is ridiculous.
