The exact origins of this item is a bit of a mystery. The inlay is identical to that used by Leisuresoft for the Vic-20. However it is also possible these tapes appeared in early versions of the Blue Digitial Fantasia boxes. It is unknown whether they were also sold alone like this, or if the outer box and manual is just missing. If you have any info on these please let us know. The roman numeral I scrawled on the inlay spine appears to be done by the manufacturer, as a second identical copy has been seen.
