FDS BIOS Dumper

This program dumps the FDS BIOS ROM (8KiB) onto a disk in 1KiB file blocks. Now you can legally obtain a dump from original hardware!

Usage

Simply boot the program (from a real disk or a drive emulator) and it will automatically dump the BIOS onto a disk. Should any issues occur, an error message/code will be displayed. Make a note of the error number and reinsert the disk. The program will retry from the 1KiB file block it failed on.

Building

The CC65 toolchain is required to build the program: https://cc65.github.io/ A simple make should then work.
