Thanks!

Is there any advantage of using the bios with syscalls over the nogdrom bios?

"nogdrom" BIOS need only if you removed GD-ROM completelly, because original BIOS hangs in this case.

Ok thanks!

I tried the nogdrom bios and there's a slight delay when booting but no big deal.

Also without a gdrom drive i get a problem with the sound. Is there a way to fix it without installing an active crystal?
