My thanks for these files, but kiwi6 has become unusable as of late, meaning the sound files don't work. I've used github to assemble my custom sound and music after that incident, even though it was pure chore to replace those I already used from kiwi6. The Dropbox files on the other hand, work perfectly. However, I just remembered something. The Begin Investigation popup, the Investigation Complete (From either GK or GK2, doesn't matter which), and the respective ones for Logic Chess from the English translation, with all their respective sounds (if any new ones are used for them, that is). I also looked for these, but I never found them. I do agree, however, that the site needs those assets for a quality of life.
As for those files, and hopefully the others if you have them, or know of where I can find them, I can't thank you enough!
