For those who asked, NYGM 3.6D is still available on the NYGM site:
http://www.subsim.com/mods1/nygm/NYGM3_6D.7z
It is no longer listed in the available list of mods on the SubSim-NYGM page.
@Walleye:
Nice work, and I'd be very glad to receive your amended files if you can post them somewhere.
Can you just clarify, please, what you mean when you say:
"NYGM HiRes Subs integrates by merging the NSS_Uboatxx.eqp files."
Are you overlaying the eqp files from HiRes subs onto the NYGM3.6F eqp files, or vice-versa?
