Hi all,
fairly new here but I would like to ask about multimap on ME7.5. I struggle a lot to create a routine to point to the desired maps. I can create in an empty space maps for LDRXN, KFMIRL etc but I find it difficult to understand how to create the routine to do point to those maps. Is there a patch available or someone who can guide me through it. If I understand that correctly I can create an XDF and share it whith everyone
TIA

why you need to change KFMIRL?
There is a easy hack to change between LDRXN and knock LDRXN

Doubling the maps isn't complicated; calling them is another matter—coding, disassembly. Reading the topics in reverse engineering will probably help you. Or find a pre-existing multimap file to understand, but don't copy it, of course; it won't work if it's not the same hardware/software...

I know. That was my initial question. I find difficult to create the function to call the new maps. I read some threads in this forum but I do not understand how to locate the variables in assembly. What I asked next on BlackT was what is the "easy hack" to switch between those maps.
I guess I have to spend more time trying to understand the assembly code (regret I didn't focused on that lecture on my uni years)

LDRXN = 0x28A38 and axis on 0x28A18
LDRXNZK = 0x28A7A and axis on 0x28A5A

At 0x8B616 you have 9A 52 0D A0
Change it to 9A 08 0D B0
You can now switch betven ldrxn and ldrxnkz with crusie switch
