====== zzt32kc ======

zzt32kc is a hex edit of ZZT 3.2 created by Spectere for widespread use. It was released on March 31st, 2019. It is notable for two reasons:

  * It is most likely the final hex edit of ZZT made for production use, with the Reconstruction of ZZT's release in March 2020,
  * It is one of the few hex edits which modify assembly code, not just data/strings.

===== Documentation =====

>Hey all! Here's a fairly simple patched version of ZZT.EXE v3.2 that bypasses
>the input and color selection screens, eliminating the need to press K, C
>every time you start the game. This does not support any alternative
>controller types whatsoever, so if you plan to use the mouse or joystick at
>any point in time, make sure to save a copy of your existing ZZT.EXE.

===== Changes =====

Code is changed between 0x1E6F and 0x205D. This concerns the area of code starting from the ''InputInitDevices;'' call in ZZT.PAS's GameConfigure up until the end of the procedure. It is replaced with the following assembly code:

<code>
    C606CC8800        mov byte [0x88cc],0x0
    C606CD8800        mov byte [0x88cd],0x0
    C60614A100        mov byte [0xa114],0x0
    89EC              mov sp,bp
    5D                pop bp
    C3                ret
</code>

which translates to:

<code>
    InputJoystickEnabled := false;
    InputMouseEnabled := false;
    VideoMonochrome := false;
</code>
