I haven't played the US Neo Geo BC, but SNK/P USA have been notorius for awful translations glitches & bugs. I'd imagine their's some bad Engrish lurking in the game somewhere.
Bad Engrish doesn't bother me with fighters so much, but the Card Fighters game for the DS was unacceptable. The Euro version of KOF XI was also shit. Words running off, the game freezing, etc.
The load times in the Japanese version were also long. So this isn't a new thing.
