Many PS2 discs contain blank data used to fill physical disc space for better reading speeds on original hardware. Compression tools strip these useless files.
To find the file you are looking for: Search specifically for (remove '2004' to avoid confusion, as the cover art will confirm the year).
Thus, the holy grail is an file that is under 700MB (fits on a CD-R for softmodded PS2s), runs faster than the original, and includes optional quality-of-life patches.
