I would love to see that game here too, but I belive it will not happen soon. I belive there is distribution model in market for retro games for retro consoles where developer/publisher on purpose decide to release only small amount of carts with his game. Why? So the price could be very high and game become instant legendary/rare . I think it is bad model and I do not understood it perfectly. I know that new games on cartridges usually have extra chips with extra code so those games can not be dumped and played in emulators, I am fine with that as long as game in future will have its PC release otherwise it will be not preserved and exists only in rare amount of physical copies.
