 Part of Digital Eclipse's work include their own Eclipse Engine, a tool that allows them to decompile the code from older games into a machine-readable format that is then used by the Eclipse Engine to play them on modern systems.While it may take some extra work by the company to decompile the older game into the proper format one time, this approach allows them to rapidly port the Eclipse Engine version to any modern gaming system, including personal computers, consoles, and portable and mobile devices, with minimal effort.This engine has been used in Digital Eclipse's "Mega Man Legacy Collection" and "The Disney Afternoon Collection".
