XDELTA and UPS/IPS/NINJA have very different purposes.

XDELTA is, as the name would suggest, a delta patching system. Rather than applying changes directly to the file, it uses the source file plus a series of instructions to generate an entirely new file. This makes it possible to create very small patches in instances where data is moved within a file.

It is well suited to PlayStation and Nintendo DS games, though more challenging to implement from a programming perspective.
