This player plays modules created with MED v2.00 to MED v2.01. This format have both a real module format, where song data and samples are combined into a single file and song+sample format. The player can load both types of files. For song+sample format, you need to have the samples beside the song files. The player will load the samples from a folder named "Instruments", which should be placed in the same folder as the song files.
