if i were to invest in anything, id want a legit physical copy of the ps2 golden wind game. and the necessary hardware to run it of course. it officially was never released outside of japan and thus not officially localized in any language beyond japanese. but an english unofficial patch exists (tho i'd like to play more games in spanish too.) so.. technically, with enough working with the hardware, software and such, it could happen?
its much easier to just emulate it, sure. But the novelty of owning an often forgotten part of JoJo history, which really only got more well-known thanks to part 5's anime adaptation, is still cool.
