I've gotten the NECD/SDL to hold the bios in memory now. There is no bios in this release. I have replaced the old source download with the new one. Changes include: Controller bug fixed (thanks to fosters for the code fix), total full screen display, graphics zoom is now centered on Puzzle Bobble, and League Bowling now works! New to the credits is speud, for helping with the ramdisk fsopen routine example.
Now that the bios is loading from the CD, you MUST wait for at least 15 seconds before swapping the disc in. I recommend waiting untl the music is finished playing to be on the safe side.
