Any way to avoid value change in memory address permanently

fstarred · 12 August 2020, 12:18

I'm currently using WinUAE debugger for finding cheats in game.

Now, suppose I want the address XXXX to have value 99 fixed, so any way I start game I don't need to manually change it on debugger.

Is it possible ?

PS
I'm not sure this is the correct section to post, in case sorry for the mistake

Yes. Its called training the game.

You need to find the instructions in the game that directly access the address for lives etc.

Requires coding ability in asm

Galahad/FLT yes I know how cheating works.

My question is: - once I found the correct address - is there any way to avoid value change of that address each time I start game?

To better explain, something similar with mame, where you can store scripts on a xml file that do the stuff automatically (for example force the address value to xx).

sorry this isn't MAME. But if you have the game running under whdload you can use a trainer or request one

from winuae, use a memwatch (w 0 address 1 W) to see where the address of lives is changed, and NOP the instruction. You can store the script in a text editor to paste it in winuae debugger at game startup (that is: if game is using the same address everytime, which can be false)

You need to code a patch which loads the game binary using LoadSeg(), apply trainer patches and start the game.

Short version: Requires coding ability in asm as Galahad already pointed out.

Thank you all for the hints

Memwatch points support it (f "freeze" parameter). It is listed in short debugger help listing (h)

Here is something that probably does what you want: http://eab.abime.net/showthread.php?t=95606
