The goal of UPS is different from NINJA / xdelta / etc. It is designed to be a direct replacement for IPS. 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. But thanks to a condensed pointer encoding method, the file size can be infinite. UPS is completely future proof in that regard.
This original UPS patcher is called Tsukuyomi UPS. The name is an homage to one of the most well known and polished IPS patchers around, Lunar IPS by FuSoYa. (Tsukuyomi is the name of the moon god in Japanese mythology.)
byuu, the author of this program, has more recently put out an updated UPS patcher, upset, as a replacement for Tsukuyomi UPS. So if you are using Tsukuyomi UPS it is recommended to use upset instead, if you are still using the UPS format.
byuu has also come out with another patch format called BPS that he recommends over UPS, and originally he put out his patcher beat for BPS. However, more recently, because beat is slow, his homepage now strongly recommends that people using the BPS format use the faster program Floating IPS by Alcaro for creating and applying BPS patches instead.
