Unused Mileena Portrait:

Image

As we all know Mileena was not included in any build of MK4 (excluding MK Gold). 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.

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 of all unused content found for this game (revision 1.0) can be found here.

But is possible play MK4 working 100% good in MAME?

Eh, it runs ok but it could be a lot smoother. The most noticeable problem in emulation is on certain effects that require the alpha layer for transparencies like Sub-Zero's ice mist that surrounds his body. You can see for yourself how it runs on an i7 2600k with 8gb of ddr3 by checking out this playlist.

Right.

I hope that in the next MAME versions this bugs will be corrected.

Pugsy, letting you know I get an error when loading your last update to the cheat file in Mortal Kombat 4 (version 1.0):

Version 2.1 and 3.0 seem to be free of this error. Wanted to make you aware before you push this latest update out.
