Posted: Sat Jul 09, 2022 1:11 am Post subject: HELP:allocateSharedMemory failed

Code:

newmem=allocateSharedMemory("newmem", 4096)
r = registerSymbol("newmem", newmem)
print(newmem) -- print nil

situation: i open two games and two CE, i want to inject some code to both games.
the game need to activate cloak before injecting code.
when i activated cloak and injected code on A game (jmp newmem),B process's code will also become "jmp newmem".

but B process doesn't have "newmem".

so i think i should use allocateSharedMemory to allocate "newmem".

but allocateSharedMemory worked on tutorial,not working on my game though.

i found your reply in the topic t=615152&view=next&sid=3cd67294fab9d88632912bf21d15cbe1

you said

Quote:

But since that is tricky I recommend just doing a single
Code:

writeInteger(address,readInteger(address))

this will trigger the copy-on-write giving the selected process a unique physical address for that page but won't trigger any integrity check.
You then apply the cloak to that new physical address

this is my script

Code:

address = getAddress("00A03719") & ~(0xfff)

PA=dbk_getPhysicalAddress(address)

print(PA)

writeInteger(address,readInteger(address))

PA=dbk_getPhysicalAddress(address)

print(PA)

dbvm_cloak_activate(PA, address)

i run this script in different ce with different game process, all prints "11795660800", nothing change.
Did I do something wrong?

sorry, i just want to inject code to both games correctly,because they will affect each other when inject the code.

i think i could inject code to the shared memory so they can jump to this memory,or use copy-on-write to avoid affecting other games when inject code to one game.

when i inject code to one game,the other will be affected sometimes,and cause the other game crash.
i dont know how to avoid that correctly Sad

ok. Disable kernelmode read/write memory and when you write memory then, it'll only affect the target process (Assuming you're targeting an actual process, and not an emulator like bluestacks, or physical memory) _________________ Do not ask me about online cheats.

thanks! but how to "Disable kernelmode read/write memory"..

besides,sometimes i can inject code to both games correctly
the code looks like:

Code:

originalcode:
jmp newmem

it works fine,it actually jump to newmem.

but after a couple minutes,i found it didnt jump to newmem anymore.
it jump to a random memory(i make a breakpoint and step over) ,despite it still show "jmp newmem".

(sorry,i cant upload img,i try my best to describe my problem!) Embarassed

there is my script

Code:

address = getAddress("00A03719") & ~(0xfff)

writeInteger(address,readInteger(address))

PA=dbk_getPhysicalAddress(address)
print('PA = '..PA)

dbvm_cloak_activate(PA, address)

local file = assert(io.open(codeFile,'r'))
local code = file:read("*all")
file.close()

autoAssemble(code)

Quote:

most likely it's a dll being reloaded

you could use a timer that checks every few seconds if the code has been restored and then rehook

edit: so i found this topic : t=590473
it's similar to my problem.
but when the game reload the dll, all game processes will have the same physical address. what i want is different games have different PA, so they will not affect each other
what i can do to change physical address or prevent it to be changed? Embarassed
