Controlled Corruption: Phase-based Comparison of Dummy Data Replacement









Each image has been corrupted in an identical manner - after an offset of 0x800, the value 0xC5 replaced a byte every 200th, 201st, 202nd, 203rd, 204th and 205th byte within the body of the file, respectively (i.e. with the first file, every 200th byte was replaced with 0xC5; in the second, it was every 201st byte etc).

This resulted in similar glitches, whereby the input and glitch parameters were very precisely controlled.
