Abystus' Codes

[Abystus]

if im remmeber corectly, the psx version may caused crash immedtly when we play as kitana:P(you only can see her at liukan stage,other stage will crash), its kinda weird becoused you can see her model at leash 3sec only:P, so its unplayable:P, if we see it playable its consider as an mod, not via cheatin:P(like pc ver), noy sure on n64(i dunt ever play 64:P)

I only remember the model for Kitana being in the N64 version only as the PSX version had FMV endings (models for these endings that weren't in-game characters were discarded). For the PSX, I believe her move set was the only thing that existed in the game, and had to be applied to another character to use her (I believe people used Shinnok from the codes I remember.). The N64 version actually used her model (from the ending as it used the same setup as the arcade game), but had her moves weapons and fatalities properly attached to the model. Unfortunately, she had no tower portrait, so the game would crash if you used her in single player mode.

Kitana should be in there because her model is used for Liu Kang Ending.
(Kitana in MK4 for N64 playable with GameShark)

That is true, but the problem is in this revision there are no character endings (1.0 was the first public release that had a lot of missing features such as character bios, endings, fatalities, and even some characters had no moves or weapons). Tanya is present in this version, but I'm not sure if they had even created the Kitana version of the model during this stage of the games development. Even if i were able to get an existing model for her to load (if one exists), it still would most likely have no move set associated with it. I have been reading a bit online about the development of the game, and from what I've seen Kitana became Tanya so that they could have more "new" characters in the roster. I'm sure the Kitana present in the ending is just a pallet swap of Tanya, but then again it may be an entirely different model. I am on the lookout for the address controlling which model to load (I'm sure there is way more than just unused character data present within the game at this stage in development). It should be an interesting find if anyone ever uncovers it.

Take your time, I was just throwing out some ideas.

[Abystus]

Could you try a move modifier and perhaps maybe her data is there that can be mapped to another character?

Well i'm not sure she is actually in the game as it's hard to tell due to some areas of the game having a fail safe coding to them, but the rest not having anything to protect against going beyond the normal values. The reason her portrait shows up is she is most likely the last portrait in the list beyond value 0x0C (she shows up for both values 0x0D & 0x0E), which is probably one area they forgot to protect initially, and is why that image shows up instead of using Scorpion. Id assume the character data loaded is just a place holder for what would be later used for Jax and Johnny Cage in the next revision. The thing is, the game defaults to scorpions model and win name printed on the screen when the normal value is exceeded, but it may be possible that other models exist if I can find and disable the code auto correcting the model used. That being said, the image was completely removed in future builds beyond 1.0 that I can tell as it does not force her image on the tower when going beyond the game's limitations (most likely deleted once they realized it was still in there). I do believe she was initially planned for the game due to the image being completely unique to any other MK game featuring Kitana (using her UMK3 costume), though from what I've read they had a lot of problems jumping from 2D to 3D on the brand new at the time ZEUS hardware, so I'm sure they most likely just ran out of time.

I am going to give this game one more look over for any possible models, move sets, weapons, tower images, and hidden screens that may be present but disabled when I get a bit more time.

I was able to successfully re-activate the disabled character bios screens in this early revision of the game (character bios were not enabled until revision 1.44 which is not currently emulated in MAME). They contain very funny non game related material, and were never meant to be seen by the public.

A playlist including these unused character bios can be found here. Enjoy.

Unused Kitana Portrait:



Unused Kitana Video:

As we all know Kitana was not included in any build of MK4 (excluding MK Gold), and was only discovered hidden away in home ports of the game (N64 & PSX). Now there is actual proof that she was originally going to be part of the arcade roster, but unfortunately was removed completely in revision 2.1 and 3.0 along with Noob Saibot getting replaced with Reiko.

Noob Saibot Playthrough:

Disabled shortly after beta builds of the game, Noob Saibot is still in revision 1.0, but is not select-able via the character select screen in this revision as he once was in previous ones. He seems pretty well in-tact as he still has his tower portrait and moveset, but is lacking many moves he would later obtain in home versions of the game. He was completely removed in revision 2.1 and 3.0 being replaced by Reiko.

Funny Character Bios:



These were later replaced in the next revision 2.1. Character Bios did not play during 1.0 attract mode, which is why I assume they left them in the game.
