This version runs entirely offline inside a custom version of UPR. Simply run the JAR, drag and drop a vanilla copy of Emerald (USA) into the app and have the ROM fully patched and randomized in seconds. Of course, random warps are optional, this will work as UPR compatible version of Emerald with Gen 9 mons too.
