XDELTA is a patching format, similar to but different from IPS, UPS or Ninja. IPS is unable to handle file sizes bigger than 2MB, so XDELTA is a popular alternative when patching CD images. (Ninja and UPS may be better in some instances but they haven't been around as long as XDELTA, so they haven't gained the same level of popularity.)

This site doesn't appear to host XDELTA but if you Google for it, the very first hit will be the official development site, which includes downloads. (And the fourth or so hit will be the Wikipedia page, if you're interested in more information about the format.)

What operating system are you trying to use it under? Also, I don't own any sayings.

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.
