Reading Memory

[you8mysandwich]

Hey guys, sorry for my poor english, hope Im still able to describe my problem.

I wanna read some variables in the memory of the game I start with WinUAE. This time it's Death or Glory: The battle of Morgan.

I wanna be able to change some data like the Healthpoints, attack and Defense. No, it's no cheating coz I'm not able to finish it, just coz I already finished it a lot of times and everytime, in the last level it crashes. Just nothing happens anymore and now I got a new version and want to test if it's possible to finish it. (Used HD Version on WinUAE and on the original Amiga 1200, both crashed at the same time.)

So, is it even possible to read something in the WinUAE games memory? Since those doesnt use the Windows memory path.

By the way I would appreciate, just incase someone got an idea a link or a hint where I can find a version with what I can even use the add on - "Der dunkle Kaiser" aswell.

Your -

Press shift + f12 while the game runs in WinUAE. Also have a look at the save state feature on the misc panel (raw dump).

You're awesome, I'm gonna try this and tell you, if it worked.

Oh, what the hell. Alright, TheCyberDruid, I just pressed F12 + Shift, got in the debugger mode and just see one window with some stats. Like D3, A4 etc. Are those the variables? I cant see more like 20 maybe, aswell, as I cant exit it except with "Quit" and this closes WinUAE completely.

How can I change variables? How can I see all variables, if those arent all?
How can I exit it, without quitting WinUAE?

You're welcome and have another look here : http://eab.abime.net/showthread.php?t=52100

Edit : I think you got the wrong idea of 'variables' here. Sorry, don't have the time to explain it properly, so I hope someone else can help you.

Hm, I just give em example:
7C405DE - 21

The code is Ceranos Mana (some Hero in the game) and 21 the points. With this knowledge I was able to change the 21 to 99 and have this Mana ingame.

Okay, then you got the idea

Alright, but those questions weren't answered yet:
How can I change variables? How can I see all variables, if those arent all?
How can I exit it, without quitting WinUAE?

These are CPU registers.

To write into memory, use "W", to exit the debugger use 'x'. You can also use "?" which will display a short help.

Thanks a lot, Im gonna try this.

Alright, this worked so far, but if I wachted once with example "C 28" and keept on, when I changed that ingame value to 14 with "g" and then "C 14" and it doesnt find anything, it keeps watching in the results it found before.

It used to work like that:
C 28 (looks for the value 28 in the memory)
found 78.285 (it found 78.825 results)
g (just search in the 78.285 results)
C 14 (I edited the ingame value, e.g. gold from 28 to 14 and now look for it in the 78.825 results)

You're doing that changing until you have one final result and this is your gold. (Those ingame values are mostly stored in there)
Then you change it and have fun with it, but it seems as I cant reset the search.
Anyone solutions?

Use 'C' without any parameters to reset the search.

You're my hero, thanks a lot!

It is working for Amiga games. I was able to give Raven, instead of 28 Attack Power, 53 Attack Power. Thanks for your great help Cody, Sting and Druid!
