You don't need the patch to play the translation. In relation to the version though, I'm afraid I don't remember since we just grabbed the latest version from the patch maker's discord at the time. The only differences should be fixed bugs and newer features.
Nice work on OFF: Forgotten Dreams!
Although an official remake is coming, I still really appreciate a lot of work that was put into this project!
By the way, I wanted to find a way to DM you some way but I couldn't find any socials attached and I'm not sure if you use twitter. There's something I wanted to talk about relating to RPGMaker.
