/******************************************************************************/ /* 3.3) Famicom Disk System Notes */ /******************************************************************************/ You will need the FDS BIOS ROM image in the base FCE Ultra directory. It must be named "disksys.rom". I will not give this file to you, so don't ask. Two types of FDS disk images are supported: disk images with the FWNES-style header, and disk images with no header. You should make backups of all of your FDS games you use with FCE Ultra. This is because FCE Ultra will write the disk image back to the storage medium, and the disk image in RAM might have been corrupted because of inaccurate emulation(this case is not likely to occur, but it could occur).
