Meridian Advance is a modular program that is used to emulate the sound systems of various video game systems. It does this by using different modules which interface with the main program to emulate these systems. This allows for the creation of a new module that can be added to the collection without any updates to the main program. Meridian Advance also supports the use of DSP plugins which allow for post processing of the output to include various effects. There is also the built in ability to record all output to a WAV file while still listening to the music as it plays. Finally, Meridian Advance also has the full support for user created skins.
