bballplay035, you could try pressing F4 once before trying to save/load (this turns on SIOIRQ) and if that works then you may need to press F4 once again after the save/load to proceed with playing. I hope that helps, but it may not because I have Tenchu 2 and I don't have to do anything to save/load normally. BTW I'm playing NTSC US version so that may be the difference if your playing PAL version. And of coarse as Rargh suggested the save states will work very well for you. Once you beat the game just make a save state of it and then you'll be able to go in and play any level you want.
