Actually, I just realised that the voice samples in this game are different to the ones in KoF98. <_< The music is definitely used in both games though.
Also, despite being based off the SNES game, apart from the main theme the music is different and there's no "Round 1... go!" voices or anything in that game. BTW, I find it odd that they'd port a game that was only released in the US. Then again, Hummer Team did the same thing with the MMPR game on the SNES.
