Considering the original developer severed all connections with other MSX groups prior to the sale of these disks and the disk labels are retouched/redrawn it is very questionable this third party distribution was officially authorized.
The label design is same with the Mes Libres one though the disk proper is not their standard green one. The contents of the CD is unknown. The bundled Wonder Witch leash cord suggests a tie to the Wonder Swan environment on which Judgment Silversword was released by M-Kai.
