This padding is specifically designed to be non-compressible. It is a collection of random 1s and 0s that prevents standard ZIP or RAR archiving tools from achieving meaningful size reductions. Therefore, the first step in compression is not archiving, but "scrubbing". A compressed ROM is useless without a powerful
