Cassette versions of other albums, they are super obscure with very few references about them.
In most cases there is just a note in J.G.M.L. But since we have PCTB-00003 and PCTB-00008 I think they are real releases we could safely add.
I'll keep digging for more info, maybe you Yahoo Auctions experts can find something else.
Here is an image with 25P5-0001, 25P5-0002 and (supposedly) PCTB-00001.
