This code ONLY works for the MS - DOS version. It will not work on the windows version. At the dos prompt when you are about to type the name of the EXE file eg :- C:\MKTRIL\mktril.exe(I am taking "mktril" as the name of the EXE file) type these parameters- /f_1buttSo it will look like this :

C:\MKTRIL\mktril/f_1butt

Now play a game and when it says "finish him/her" go as close as you can to the opponent and press :

High Punch for the automatic Brutality

Low Punch for the automatic Babality

Block for the automatic Friendship

High Kick for the automatic Fatality 1

Low Kick for the automatic Fatality 2

Run for the automatic Animality

This code works only for the DOS version, not the windows version:

At the dos prompt when you are about to type "mktril.exe"

eg:- C:\MKTRIL\mktril.exe

Type this parameter - /treasure

eg:- C:\MKTRIL\mktril/treasure

And you will start with the treasure chest which you normally get only when you finish the tournament mode.
