The ECM format allows you to reduce the size of a typical CD image file (BIN, ISO, CDI, NRG, CCD, or any other format that uses raw sectors; results may vary).
It works by eliminating the Error Correction/Detection Codes (ECC/EDC) from each sector whenever possible. The encoder automatically adjusts to different sector types and automatically skips any headers it encounters.
The results will vary depending on how much redundant ECC/EDC data is present.
Instructions:
-- Make sure you have all the requirements (Check the Requirements page here.)
-- Run the application.
-- Select a mode (File to ECM or ECM to Original)
-- Select the file.
-- Select the output folder.
-- Click convert.
A console window should apear after clicking "Convert", do not worry, it is doing it's magic.
Special thanks to Neill Corlett for making the encoder / decoder.
