I have spent a few days hacking away at revision 1.0 of the game on MAME, and have found some pretty interesting things. I have recorded most of my findings along with releasing the cheats I created to access the content.

Things found:

- Kitana (Tower portrait only unfortunately. Was completely removed in 2.1 and 3.0.)

- Noob Saibot (Not normally select-able. Was completely removed in 2.1 and 3.0, but had been playable in earlier beta builds.)

- Unused Character Bios (Revision 1.0 did not have these enabled, and for good reason. These were later fleshed out with the real character bios in 2.1.)

Anyone interested in seeing my discoveries can check out the playlist below:

Enjoy.
