I assume he's talking about the PSOne version. The PC version does not run from the CD.
Anyway, sorta. You just have to find the various filetables. They're normally little-endian lists of LBA+Size. There's some in the YAMADA.BIN - you might find it productive to search through files looking for values that fit the LBA-Size format in the YAMADA. Use CD Mage to find the LBA / size values themselves, but remember that CD Mage will list them in decimal, not hex.
How easy you will find this is another matter. Really, the best person to speak to would be Gemini, but he doesn't spare much time to individual requests.
