How do I use DiskSystem emulation in iNES?
First of all, you need to have a file called DISKSYS.ROM in your current directory. This file should contain the DiskSystem BIOS of 8192 bytes in size. To run a program from an .FDS file, open it as you would open any normal .NES file. iNES will start with the disk “removed” from the “drive”. To insert the disk, press [BACKSPACE] and release it. The boot-up sequence will start. Every time the program asks you to change the disk side or put a next disk, press and release [BACKSPACE]: this will simulate disk removal/insertion and also switch iNES to the next chunk of data from the .FDS file. To skip to a certain disk (or side), press [BACKSPACE] multiple times.
