WinUAE memory editor

Yes, when you've found values you can freeze them with the watchpoint command:

w <watchpoint number> <memory start address> <length in bytes> <flags>

To freeze your 1E7E6 address in Crazy Cars 3 you would do:

w 0 1E7E6 2 frw

This sets freeze watchpoint 0 on the contents of that address and the following one.

The flags are (from Toni):

FR = writing changes value in memory normally, reading always return frozen value.
FW = writing replaces value in memory with frozen value, reading returns original value in memory location. (of course only if location has not yet been written to)
FRW = original operation, both reads and writes are frozen.

To use another watchpoint change the watchpoint number to 1, 2 3 etc.

To remove watchpoint 0:

w 0 R

And view all watchpoints with:

w

...a bit off topic but check this thread for details about a cheat that gives you 1024 Knights in your Home Army and 1024 Knights in your Compaign Army

Thanks for all the great tips in the end.

This thread was very useful, as I managed to cheat with the Amiga games. You guys should possibly STICKY this thread.

Anyways, played out with freezing on CC3 worked just fine. I used the 'D' command to search for nitro values and it worked. Found out the address and froze it, so that was nice. Damn, I forgot how hard the game really was. Guess I haven't used those CC3 motor skills since I was a kid. Game was amazing to play and finish finally.

Anyway, I wanted to thank you again CODY for all the help it was great. I'm gonna go now and cheat on some other games. If I need some more help I will come back, but I think I figured it out how to cheat for now, which helps a lot.

ps. Thanks DamienD for the DOTC help, it was a nice thread also. I couldn't get that specific cheat to work so I just used Tsearch on DOTC. For some reason if you use it and search 1 byte on GOLD you always get a result. Then just freeze at 255 and game is yours. Make catapults, knights, etc.

Thanks again.

One more question - whether is DMA in the WinUAE?

What?

It would have to be, if it properly emulates Agnus, as Agnus was the "DMAC".

Agnus controlled the Custom chip access timings to Ram. Denise and Paula had to get "Permission" from Agnus in order to access Ram.

I wish to learn, whether changes on DMA cheat addresses in WinUAE.

You probably mean "dynamic memory allocation"? I.e. pointers?

Yes, probably, depends on game - just like in any other computer system.

The request to explain what zones of the memory (RAM) can be concerned by the cheats?
Upd.: It seems, last version (1.6.1) shows not all accessible debugger commands!!
