Resident Evil 4 & 5 PC -> [PC] Resident Evil 6 Save Editor
Played the PC version and so far the big different I've seen is in the vore deaths. Now when the character is regurgitated by either the tentacle arm or slime spitter head their upper torso is covered in a brownish slime. Also of interest is the fact that nude models of Sherry and Ada already exist in the game, complete with nipples. An apparent glitch lets you play as Sherry without her hospital gown. Exposing her goodies.
May be it seems that ada and sherry originally share the same body model so thats why sherry's nude model worked on Ada and not helena who got a more big boned body which is different from the slim bone model that ada and sherry has , but may be they can work out a way to apply this to helena :) , or may be because both has a one piece dress costume in the game (hospital costume for sherry and the white dress for ada) and may be the patch is based on one piece dresses so thats why only both of them got the nude patch unlike helena who doesn't have dress costumes in the game
Also there is a trainer that is released for this game and it really has nice features like more camera editing , invincible mode and other nice things ,
The great news is that years ago the creator of this trainer had made a trainer for RE5 that had a feature to swap models any time during the game easily with the ability to swap Both versions of Jill into the main game easily with no glitches and I used it personally with no problems so the great news is that he works something for RE6 so if this is done correctly then chris's campaign may be added to our ryona list soon :) , although the exclusive animation still might not be feminine but it will be better than nothing I think
Here is the page of the trainer if anyone interested :
