Typical features

General:

Infinite lives, invulnerability, permanent power ups, no collision detection, walk through walls, one hit kills, super-high jumps, infinite money etc.
Obtain any item in the game, even those not normally obtainable (e.g. debug or removed items).
Access or warp to any level, even those not normally accessible (e.g. test or unused levels).
Activate debug menus, normally used by programmers when testing and debugging a game. Typically options include cheats, level warping and display of internal game data not normally viewable by the player.
Download, upload, import and export save games to the Internet or storage device.
Save game state to disk, so it can be restarted from that point even if the game does not support saving.
Region-free operation.
Loading of third party homebrew applications/games, not backup copies of retail games.

ACTION REPLAY AMIGA 500 RESOURCES

AMIGA 500 ACTION REPLAY MK3 ENCRYPTION :

DISK BASED INSTRUCTIONS
appear as meaningless characters whereas a file from a word-processor may have
extra characters which are control codes for text formatting. The path and filename are
as the DELETE instruction.

P.ODF (drive) (r.nrie nnmher)

This is another rather complex encryption tool that to get fully to grips with will take
some experimentation before you will fully understand it. (drive) is the drive number 0-
4 and (code number) is a value in the range 0-165535. The easiest way to show you
how to use this feature is by example.

CODE03

will have the effect of en-coding all disk writes to drive so that they can only be read
in future by setting the drive code to 3. All reads from this drive will also be de-coded
using this number so normal files will be read as corrupt data. For example the following

CODE0
SA TEST
CODE 3
LA TEST

(remove encryption from drive 0)
(save a frozen file to disk)
(en-code disk with number 3)
(re-load the frozen file)

will load a corrupt file as a different code has been used to load (3) as that used to save
(none). The instruction

CODE
will display all the en-coded drives and an encryption number. Note that this number
will not be the same as that entered, and whether the drive is protected or not e.g. the
status after the previous command would be as follows.

ACTION REPLAY DISK CODER V1 .1

DRIVEO CODE:00000005 PRO protected

DRIVE) CODE.00000000 NORMAI

DISK BASED INSTRUCTIONS

DRIVE2 CODE:00000000 NORMAL
DRIVE3 CODE:00000000 NORMAL
DRIVE4 CODE:00000000 NORMAL

The code of 5 will always correspond to the entered number 3! This is the same for all
codes. PLEASE use this feature with care, we would hate you to save your most
precious files and forget the code number! The Diskcode values can also be viewed
from F3 preference screen.

C OnFP,OPY (source) (destination)

This is used in conjunction with the CODE instruction. It will de-code all data from the

source drive using the code number then encode all tne data g° in 9 t0 tne destination
drive using its number. You may use this feature for encoding or de-coding entire disks.
