Matches a dump from ackmed (all info is the same) and it also matches extracted CHD from MAME 0.210.
It's now verified and I had to make a new dat (Sega NAOMI - Applications) to accomodate it. :)

Thank you both for helping verify this one. :)

I will also add that this disc contains Firmware 2.17.

technically, this is a part of Virtua Fighter 4 Evolution (GDS-0024) kit, because this game require DIMM board firmware to be 2.17 (or later), also uses same security key.

same with v2.13 update GDS-0023A and Virtua Fighter 4 (GDS-0012), or v3.17 update GDS-0023E and Virtua Fighter 4 Final Tuned (GDS-0036)
