Somehow, most have ROM hackers have used a version of Emerald different from the one most of us find through online searching.Just something I've wanted to make for a while now.Tsukuyomi requires eye contact to be performed. It is said to represent the 'Spiritual World and Darkness' (精神界と闇, Seishinkai to Yami ), the antipode to Amaterasu - a ninjutsu of similar power. It is unique to the Uchiha clan and only those who have awakened the Mangekyō Sharingan can perform it. Tsukuyomi is noted to be one of the most powerful genjutsu in existence.There are several UPS patchers out there like - UPS Patcher - TsukuyomiUPS - NUPS - NUPS Mirror UPS patches allow you to expand the ROM without having to do use the dual patches method like StealthPatch, making it more efficient and easier to understand. As mentioned before UPS is a better format for patching files.UPS is completely future proof in that regard. But thanks to a condensed pointer encoding method, the file size can be infinite. The difficulty of implementing it is equal to IPS (it has trickier pointers, but no RLE magic.) The spec for UPS supports any file size, though the binary is currently limited to 4GB files due to libc limitations. It is designed to be a direct replacement for IPS. The goal of UPS is different from NINJA / xdelta / etc.
