I'm trying to make a script work when connected to Physical Memory, but every time I try to enable it, I get the following error: Failure allocating memory near XXXXXX. I've tried allocating nonpaged memory and specifying that location with the third parameter of alloc(), kalloc() in the auto assembler, and even globallalloc(). Everything results in the game either crashing or populating the aforementioned error. Any tips on how to fix this?

memory addressing is relative to virtual memory, not physical memory. A physical address has no meaning to assembler code

you'll have to hook in the physical memory into the pagetale system of the target process and then use that entry to get the virtual address

Can you open the process normally and allocate memory in there before switching to the physical memory?

Otherwise you'll still have to find out the pagetables for this process and fill in the physical memory address yourself for the virtual address you like

Is the jmp instruction correct?
(You can't let CE generate the bytes for the jmp for you, you'll have to calculate it yourself based on the virtual address origin and virtual address destination (CE would pick the physical address origin which would be wrong)

or do a 14 byte 'jmp far as those are independent on location

don't forget the jmp back to the original code as well as the jmp from the physical address will be different

and your code isn't going to jump to the physical address of the allocated memory but it has to jump to the virtual address
