I've been playing doom and noticing that sometimes the music will start clipping out when the disc drive is accessing information such as monsters spawning or weapon switching and such; I'm assuming this is not supposed to happen. I figured maybe I could add a dummy file to the cd to help speed up access times but the 3do opera file system is not mountable, at least in Linux. I know there is an openoperafs driver so I tried compiling that but it failed; I'm guessing it's because I'm on a much newer kernel 3.14. But maybe the dummy file thing is not even the solution? Does anybody know? I have an FZ-1 if that makes a difference.
Maybe you'll try to use different CD-R brand, lower speed or different recorder? Dunno about FZ-1, but i never had any problems with Doom on japanese FZ-10. Also trying to use operafs driver won't do any good because it can't sign the image for you. It's either replace BIOS (with BIOS that have RSA check patched out) or use signing tools. I have sources somewhere but AFAIR it won't compile in linux as is. Well if you still want to try to mess with 3DO filesystem, here are the tools http://cloudstor.es/f/eZ7/ Binaries will work in wine like a charm.
Well I think I may have fixed it with a different drive and speed. There still seems to be a bit of stuttering though such as changing to a newly found weapon or opening doors and such. I hear the drive being accessed so I don't know if it's supposed to be a smooth transition or not.
