hi all,

actually i try to make code injection on MAME to cheat some games that i have, but i still confuse when i do this, i just add some ammo utomatically when i use it, actually the original ammo will decrease 1 when i use it.

alloc(newmem,2048,"Mameui64.exe"+2A39949)
label(returnhere)
label(originalcode)
label(exit)

newmem:

//please help me what must i do to write here
//i just want to add the ammo automatically

originalcode:
mov [rdx],ax
add rsp,38

exit:
jmp returnhere

"Mameui64.exe"+2A39949:
jmp newmem
nop
nop
returnhere:

thanks for your help[/img]

Assuming that code only accesses your ammo and it's decreased by only 1 every time it's run, this should add 1 to your ammo every time you fire:

thanks ParkourPenguin, but its still not work, i dont know how to do it, but if i have to capture the image i am sure that you will know what the problem is.

ok maybe i try to figure it with thes way.
1. i find out the address.. then when i found it but its more than 1 address,

example i found 2 address that show the number of ammo

1936E28F and 19379721

so i dont know which address that i have to pick to "find out what what writes to this address" between that two address.

then i try to select one of them.. and when i fill the assembly code.. i got the error messege.

so what must i do.[/img]

You can start by saying what the error message is. Also, copying and pasting your code into some code tags would help.

Also, you can determine which of those addresses is your ammo by changing them yourself. If it takes effect in the game, then it's the real value. If it has no effect on the game, then it's probably useless to you.
