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

It contains tiles from Generitiles by Drag, Cavewoman by Sik, and Chase by shiru.
The NESdev Wiki, Forums, and Discord have been a massive help. Kudos to everyone keeping this console generation alive!
