In the "EAWTM2" folder there are the two default texture mapping files, "TextMap1.str" and "TextMap2.str".
I used the string editor twice and put them together on my desktop:
Corresponding lines match.
There is no PlaneMEX-PlaneMRA link, but there used to be.
For some reason it created problems with some of Iron Mike's multiskins, so I deleted it.
