Cheat Engine

i found one code ...
start auto assemble there ...

alloc(newmem,2048)
etc ...

when i enable/execute it ...
the jump to newmem ... does not bring to an actual newmem, but it uses some space ... already in use by the game ... and then, of course, the game crashes.

how do i fix that ... ? because with other codes works.
i have 7 scripts in the table with a total of:
3 globalalloc
9 alloc
many meny labels

all disabled when trying to enable/execute the code

the "jmp newmem" line must be in the same script (enable section) as the "alloc(newmem)" line

and don't hardcode the jmp using e9 xx,xx,xx,xx and also do not use the "short" modifier for this jump

And don't redefine the alloc with a define or label

I have checked ... and everything is in order.
I've forgot to say that i have other scripts that give no problem, and actually allocs memory for the code ...

could it be because there's no more free space to alloc ? All of my codes are alloced with codes 2048, so it's more than necessary ... could be that ?

The size is not a problem. 1000 of those is only 4MB

But try to use more unique names instead of newmem. Perhaps you have registered a custom name called newmem that interferes with the script. (Globalalloc registers customnames as well, and always return the same value once defined)

i have also checked the labels and alloc names, they're all different and no one is named newmem
