SDSME Adding New Map Headers & Maps to Gen 5

[Monty3540]

Hi All

I am looking at adding in some of the maps from B2W2 into BW - particularly Lentimas Town, Reversal Mountain and Seaside Cave.

I am able to remove / swap certain headers for the version exclusive areas like Black City and half of Opelucid etc - but I would ideally just add some more Map Headers for ease to retain all data

Has anyone had any experience of how to add in extra Map Headers, Maps and Matrix's into the ROM with SDSME?
I swear I need to edit the a012.bin /arm9 file but I haven't seen any examples of what to do for it.

I worked out how to add in more maps, by extracting the a008 narc and copying and pasting them in from B2W2 - however when you repack the narc with Kiwi, the order completely changes the map that every matrix is assigned too - which is a bit of a mess!

Just wondering if anyone had any experiences with this / any info that could help
