(NOTE: C2/0F6F is only called if you have weapons in both hands, which means that's the ONLY situation where the Genji Glove effect is cleared. So you'll do full damage with each strike if you have two weapons, but have it reduced by 1/4 if you have zero or one weapon. This is widely acknowledged as ass-backwards; common sense tells you that 1 weapon should hardly be more cumbersome than 2... Nor should a magic glove make gripping one a tall feat. I suspect Square was thrown by their own byte $11CF, as "set effect to be cleared" sounds like an oxymoron. They were probably trying to *enable* the genji effect below (after all, TSB usually _does_ _enable_ things). At least that's what my forthcoming patch will assume... ^__^ ) C2/0F6F: A9 10 LDA #$10 (Genji Glove Effect) C2/0F71: 0C CF 11 TSB $11CF (Sets Genji Glove effect to be cleared) C2/0F74: A9 40 LDA #$40 C2/0F76: 1C DA 11 TRB $11DA (turn off Gauntlet effect for 1st hand) C2/0F79: 1C DB 11 TRB $11DB (turn off Gauntlet effect for 2nd hand) C2/0F7C: 60 RTS
