Cheats in game run-time

Attention! This topic gives example on cheats scripts, allowing you to test and see how ones work.


There are a couple of ways of creating you're own cheats in game. The most easiest way for beginners is by using CLEO opcodes 0A8C: and 0A8D:

Using the original method

Here is a demo script which shows the way they work, type the following cheat to test how
they work.

Code:


{$CLEO}
0000:
// Example of cheats

// Testing 4 letter cheat
// Type "hack"
:Cheat_01
0001: wait 0 ms
0006: 29@ = -0x38214
00D6: if
0038:  &0(29@,1i) == 0x4841434B 
004D: jump_if_false @Cheat_02
0004: &0(29@,1i) = 0x48414300
03E5: show_text_box 'CHEAT1'  // Cheat activated
0002: jump @Cheat_01

// Testing 6 letter cheat
// Type "cheats"
:Cheat_02
0006: 30@ = -0x38213
008B: 30@ = &0(30@,1i) // (int)
0085: 31@ = 30@ // (int)
0016: 31@ /= 0x10000
0012: 31@ *= 0x10000
0062: 30@ -= 31@ // (int)
00D6: if
0039:  30@ == 0x4348

The cheat address starts at "0x969110" max for one line is 4 letters, if you want more you
need to expand the address using a different var for it.

So if the cheat is more than four letters the next time you use opcode
0A8D: the address will be "0x969114" the third parameter of opcode 0ABD: is the number
of letters it holds.

Here is a script, this script shows all different ways of cheats with using CLEO opcodes.

Code:


{$CLEO}
0000:
// Example of cheats

// Testing 4 letter cheat
// Type "test"
