Mortal Kombat (Jade and other hacked kisses)

Using codes you can give Jade another ninja girl's moveset thereby giving Jade access to their kiss Fatalities.

Bonus video of Kitana and Mileena using their Fatalities with Noob and Kintaro's palettes: https://www.youtube.com/watch?v=9aZIr5hJYn0&feature=plcp

In MK 1, 2, and 3 any character can be given any other character's moveset, but if they don't share models then they'll take on the model of the corresponding moveset while keeping their own palette. Also in UMK3 you cannot give anybody else Noob's palette or I would have included that at some point in a video.

Here's one of Sonya from MK4 using Tanya's kiss Fatality: https://www.youtube.com/watch?v=c_dBHfJ7sSM&feature=plcp

The video also contains both Sonya and Tanya using Tanya's kiss on the unfinished Kitana (basically a palette swap of Tanya with a guy's voice), only accessible by hacking.

I had to use MK4 instead of Gold for this because as far as I'm aware, no Fatality modifier codes exist for Gold and the unfinished Kitana of course isn't in Gold.

Also, here's Tanya using Sonya's blown kiss Fatality: https://www.youtube.com/watch?v=Y7RGRUVS8qw&feature=plcp
