I think I screwed up.
After finishing Trails in the Sky, I decided to start Ys X Proud Nordics last night.
While I’m still early in and only done the first mini dungeon, if you can even call it that, I did really enjoy it.

Today I kept thinking why the title just said “Nordics”.
Just looked at the box and I installed the wrong version.
I don’t even know if the save file i compatible with the improved release. I doubt it. 😭
Oh well.
I get to do it all again tonight…

Thought so… 😭

@outofprintarchive There is literally no reason the save data wouldn't be 100% compatible. It doesn't change the engine or the base game mechanics anything like that.

I guess this is just a case of the OS intentionally limits access from one to the other. Likely not limiting this game specifically, just in general I'd bet. That's a thing they do now because of the theoretical capacity for saves to carry exploits (though off the top of my head I can't think of any ever doing so in anything remotely modernish?)
