ok i think i figured out the problem as i said before, (US 980904) and (USA 980904) are the exact same game, down to the last drop. the only difference is recent mame versions renamed US to USA. players online who use the old mame or other emulators (kawaks, nebula, etc) still list the game as US, instead of USA. im guessing that kaillera does not know that (US 980904) and (USA 980904) are the same exact rom because it does not have the same name. therefore, it....well u know. wut do u guys think? if im rite, then kaillera is not taking advantage of the red queen's hypotheses.
