ZX Life Shield V1.0
30.Jan.98



1-INTRODUCTION
~~~~~~~~~~~~~~
This program was made to find lives in ZX  Spectrum  games
using the file format Mirage/Snapshot.

It allows you either to put infinite lives on them or just
to change them to  a  certain value at any time during the
play of the game.

It was made using AMOS PRO 2.0.

I have found lives in dozens of games using it.

5-HOW IT WORKS
~~~~~~~~~~~~~~
Use LEFT AMIGA+A to multi task.

How to save snapshots:

Start playing a game and the moment you are in control  of
the player  save  that  snapshot.  Lose  one  life and the
moment you are in control of the player save the snapshot.

In some  cases  like  DEEP  and  INFINITE trainer mode you
still have to save a 3rd snapshot.


Trainer Mode:
 NORMAL - You  load  two   snapshots  containing  diferent
          number of lives. in LIVES1 select how many lives
          there is is in the 1st snapshot and in LIVES2 in
          the  2nd  snapshot.  Then  press COMPARE and the
          possible  address  for  the lives will be shown.
          You can then, at any  time  during game,  change
          the  lives up to 255. Notice, however, that some
          games  crash  if  you  put  more  than a certain
          number of lives.

 DEEP   - If NORMAL Trainer didn't work then try this one.
          It works with  3  snapshots. You start the game,
          save  a  snapshot.  Lose  a  life  save  another
          snapshot and then lose a life and save another.

          This will look for address that if  in  the  1st
          snapshot  have  a value X, in the 2nd X-1 and in
          the 3rd X-2.  It  list  the  possible  addresses
          along with the  value  of that address (which is
          different from the number of lives)

INFINITE- After you found the address containing the lives
          go here  and  press  COMPARE.  Then  insert  the
          address containing the lives and this  will  try
          to find all the addresses in memory  pointing to
          that address.

          After  you  find the address, all you have to do
          is to  point  it  to a ROM address so that lives
          never decrease  (the game will try to decrease a
          value contained in a ROM address). Find the  ROM
          address  using  the  option  VALUE AT ROM in the
          menu TOOLS.


Menu TOOLS:

Word Split - If you have more than  255  lives  (or  other
             thing) in the game use this to  convert  that
             to a low byte and a high byte and then search
             for the low byte as being the number of lives.

Value at ROM - Use this for the INFINITE mode. Imagine you
               want  an  address  at ROM whose value is 3.
               Just go here and it will find that  address
               for you.

Peek into - Displays  the  content  of  an address between
            16384 and 65535.
