you're probably not going to see them
They were Japan only, and Japan seems to have declared them prototypes, even if an actual source at IGS says they were full-production budget games that simply didn't receive much advertising (because they were meant to be low-budget, shipped primarily to a foreign market, and therefore not worth promoting)
as a result the price people are asking for them has gone from about $250 a few years back to >$2000 now even if their true value should be the lower of those figures. chances are they're all sat in a warehouse somewhere.
the IGS contact also says there was a 3rd puzzle game that nobody even seems to have mentioned or documented anywhere so god knows what people will want for that now if one shows up.
