Wait........a 8-Player Mode?!?!?! why this isn't in PPT?! ('Cuz, in my opinion, any console would EXPLODE for something like this. Even for a modern console like the Switch.)
I don't think the console capabilities are the problem though, it's the fact that the DS has 2 screens, which can fit in 4 players on 1 screen just fine. 4 players on 1 screen already is a bit squished to fit everyone, so 8 would require the board to shrink to uncomfortable amounts just to fit the extra 4. This means that 8 player Puyo is only going to become possibe once stuff like 21:9 screens become *much* more of a commonality, which I doubt is going to be less than a year away.
Is this the American version of the DS version of this game? Or the PAL version? Maybe American, because the PAL version if I recall, renamed Satan "Dark Prince" or something.
The release is a fan translation by puyo nexus. It was never released international. That's why it's Satan, instead of dark prince. It's a fan translation.
