i've been trying to hex edit the money in a game called YS Oath in Felghana but whenever i attempt to hex edit the value of the money, it changes back to normal and i see no change in the game at all. I scan for the value of the money and receive an address which i attempt to edit but it changes back after i edit it when i enter the game. What could be the cause of this and how do i bypass this problem. It is a client sided game since its a single player game -_- so i should be able to edit it. Please give me ur advice regarding this problem.

Try nopping the money decrease code and then you would have unlimited money. Or try to freeze the money value, and then modify it.

Are you trying to practice hex editing or something? I mean, you are here at the cheat engine forums, I would assume you know that a memory editor would be much more ideal for simple hacks like that.

I've encountered some strange problem while trying to edit the value of the money. After i change the value of the money, the value of the money shows absolutely no change but there is a strange change in the game. The game forces you to sheathe your weapons when u enter town or any safe place, however when i change the value of the money, the sword is suddenly unsheathed and i can kill innocent npcs, also when i terminate the program it gives me an error "Program has stopped working" forcing me to restart from the beginning of the game all over again (saves are also affected) to eliminate this problem which is getting quite annoying. I see the value of the money change as i pick money up but when i edit that value i never see changes in the game. Anyone got advice on this?.

No one would really know unless they have the game and try.
It seems like you have found a shared address. I would find what access's this address and then from there you should be able to get what you need.

i seem to be able to mod the value of the money after i scan and find 2 addresses that seem to be both linked to the money but it requires me to change both of them in order to get the money to change but in addition it forces me to make a change that unsheathes my weapons which till now i dunno how to fix. I find that if i change the kernel.dll file it fixes it unless i load the save game i mod.

I have managed to hack the different resources through code injection but i can't seem to do that for health. whenever i attempt to find what writes to that address, the game crashes immediately. After which i receive 3 addresses mov [ebp-2c],edx, push eax and mov edi,edx. My intention is to cause the address that writes to my hp to add health instead of subtract it cause freezing and changing the address doesn't seem to have any affect, however i haven't achieved it just yet, can anyone give me advice on what to change in order to get it to work?.
