Harmful Park - JPN PS

Here's the 6 digits from Gamefaqs: 572983.

I tried to add the digits to a Gamespot URL, but I couldn't get it to work. I hope it's not just this work computer.

For whatever reason I can't add "The Rumble Fish" on PS2 to my collection. It comes up as TBA which makes me think it's the unreleased US version, but I do own the Japanese version so I was wondering if that could be added? I'd also like to add "Onimusha Buraiden" and "Devil May Cry" the Japanese version to my collection. Here's more info on each game:

Is it ok to ask for more Japanese titles to be added?
