These findings are unrelated to the gigaleaks and began on a mere Google search of "Texture CD 1994" translated to Japanese and a lot of luck.
If you wish to find new discoveries yourself, the CD's listed here may still have matches we didn't notice.
These pages contain the sources of material and audio asset libraries that are used in a wide range of media. Their usage is documented which dates back to the 90s all the way to present day.
The pages listed below are undergoing construction still, expect messy grammar or missing details.
