I am currently uploading dumps for japanese PS2 games that are not found on this site to a cloud drive of mine.
This pastebin includes some of the games and their MD5 hashes. https://pastebin.com/a9HHzapC
Let me know if you are interested.

Are these the images taken from the internet and not dumped by you? Nope, no interest, then. They can be damaged, altered or taken from the pirate discs, we can't rely on unknown sources.
