Emu XL-7 & MP-7 User's Group

I noticed that the rom from my mk-6 (which currently lives in my XL-
7) name is 'MROM'. I looked in the manual for the MP-7 which its rom 
is named 'MP-7', yet both have exactly the same presets..I suspect 
the same is true for the XL-7 and XROM1  (although I havent 
checked)..My question is - are their ROM IDs the same just named 
different for different product lines - allowing them to be used 
interchangably ??
