I discovered something looking through files in evtmov2.pac in Legends (which contains ring entrance nameplates for arenas.) I really liked using denbigh's old school arenas, but didn't like how they still contained the ECW nameplates. I discovered that files M070-M079 (which were nameplates for custom arenas) had been modded, but not in use. They are:
M070 = old school wwf logo nameplate
M071 = new gen wwf logo nameplate
M072 = attitude era wwf logo nameplate
M073 = wwe logo nameplate
M074 = red/blue generic lines
M075 = blue nwa
M076 = wcw purple w/ globe
M077 = wcw 99 logo
M078 = wcw invasion logo
M079 = black/silver generic block
Using XPacker, I simply extracted M075 (the blue NWA nameplate) and injected it into M012 (the slot denbigh's NWA arena replaces, which was originally ECW November to Remember) and loaded up the game, and now I have a NWA nameplate for my NWA arena. It feels more authentic.
As well, M074 has a red/blue generic nameplate that would be good to use for denbigh's AWA arenas. For the WCCW arena, I may try to see if the nameplate from 2k17's WCCW arena would work.
