Nes-Extract is a command line application for extract PRG & CHR Nes/Famicom rom. Result can be burned directly into an EPROM for real hardware test.

The features I have added are:

• Detect correct input file ( extract only if files have NES/FC Header).
• Create separate files for PRG & CHR or rewrite it if already exist..

./NesExtract rom.nes

• First read the header file and collect PRG and CHR size.
• Then malloc two buffer with collected size and send data inside.
• Finally write the result files with buffer content.
