A must have for editors

Reviewed By: KPax1585 on 30 Jan 2016

This program has helped me when I first started editing console games about 10 years ago, it also will help those who may have multiple copies of the same game (when using this and a duplicate finder). The Only downside is that you can only do one game at a time, but that can be overlooked when compared to the alternate: hex-edit search and modify.
