PS2 Japanese/ English converter

I have heard of various reports from this forum that there is a converter that allows one using an english PS2 to play games for the Japanese ps2/ ps1. What I want to know is:

1. If it is real.
2. How much it costs and where I could find it.
3. If it translates into english or just allows me to play Japanese games.
4. If To Heart and To Heart to are for the Ps1 or PS2.

I would love answers to any of these questions.

1. It's real but involves breaking off the front of the disk tray, just get it chipped instead.
2. Try eBay.
3. Errr, no. Thats just not possible.
4. Sorry, no idea. Check gamespot.
