I've never played any version of either of these games, so maybe someone who has can shed some insight.
I know one of the reasons these two games were chosen by SFT to be translated and released for Western audiences was the lack of reused/stolen/unauthorized content when compared to other MD games.
Are there any assets like music, FX, sprites, or other stuff that are straight-up lifted from other licensed games? If so, was any of that changed for the SFT release?
What about the music, does it have recycle stuff from previous unlicensed MD games?
