A version of Jak X, 2 months before final. Has differences everywhere, most are minor, some are more obvious.

This video shows most of the major differences, but not all of them. Some other differences are mentioned in text later in the video. Some are not mentioned at all. Some are unknown even to me.
More information are in the video.

I recorded in 4:3 because that is the most optimal aspect ratio for Jak games, and this gave me space for a sidebar where I could note some things down.

Most of the music was added during editing. When that is the case, you will see a small text telling this in the bottom right corner.

I made a Debug Mode patch for this build (involved the usually disassembling pain in Ghidra), it is included in PCSX2-Sanity: github.com/LuminarLight/pcsx2-sanity
It should make exploration and research of this build much easier. Just don't try to teleport away directly from the main menu, this build can get stuck if you do that. If I figure out a fix, I will update the patch in PCSX2-Sanity.
