geometrics

everything was working fine, i was playing ikaruga, died and saved.. then after that, i try to boot it up again and in the black screen behind the nulldc, it sais error in save blah blah etc.. about fifty times, and it just takes me to setting the time in the dreamcast bios.. anyone know what happened? and what not to do next time? haha, thanks again.

now, i switched from Chankast over to nulldc because i experienced too many problems with chankast. nulldc seems to be more friendly, giving a variety of options to help customize your graphical and audio settings.. now, i'm playing ikaruga, and everythings fine, but by the second level the sound begins to get choppy, and i get a bit of a slow down graphically here and there. what might you recommend setting wise to utilize the best performance? here are my computer specs: geforce 6800 gt 256 mb agp 8x windows xp AMD 64 processor 3000+ 2.01 ghz, 512 ddr ram any help would be greatly appreciated, cheers.
