That helps a lot! Thanks! I don't have a Japanese Super Famicom to play them on (I only have a SNES mini which I've never even tried out, I have no idea where it even is) but I can at least try them out with emulation.

They had multiple copies of Romancing Saga 1 & 2, which I don't think would be easy to play without the ability to read the language. The booth had probably 30 to 40 cartridges. If I hadn't spent over a hundred bucks at the supermarket an hour before, I might have bought more than four cartridges.
