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

Hi.
I removed the sound Rom from my MP7 to give it to a friend who 
has a P2000 and he gave me his Composer Rom. Once 
mounted the Roms in place, I initialized all user presets 
because they were now allocated to wrong waveforms.
Since now I have all blank presets in both machines, how exactly 
can I now get the presets of the P-2000 in the MP7 which has the 
Composer Rom within, and how can I load the MP7 presets into 
the P-2000 which now has the Phatt Rom?
Will E-loader do the job for the P-2000 too? And how?
I mistakenly thought the Rom carried a preset setup within it.
Thanks.
Max
