Does 3.3 work with regular SIMMs and a SuperBios ?
I have seen this issue on a mobo, all other games worked but not 3.3 (backgrounds garbled, sprites and musics all OK).
With a SuperBIOS the SIMM6 & 7 showed the same data !?
Issue with SIMM6 slot I guess, or a custom chip.
Ah ah didn't want to answer because the condition of mine was not comparable : I think the label on the front of the cart was a repro, and the mobo had a couple of minor comestic issues.
Buyer was aware of these of course.
On the other hand it did include the original english version CD inlay...
To me it seems that none of the recent ports (legit or otherwise) of scarce boards (or console games) have made any dent in the original game's prices.
Gamers will go to the ports, but there will still be more collectors in the market to buy a given game than there's offer available.
