PRG ROM

The NES File header (ines hader) need to be added to the PRG ROM. Because the header does not belong to the ROM but is needed for emulators. (+0x10)

More info about the header here: https://wiki.nesdev.com/w/index.php/INES

(all of these here are add 0x10 for header)

Things I would like to research and add

Sprite assembly format and animation format. May be a enemy editing file.
