Action Replay 2 uses 10 (I think) digit codes which you can find at
www.codejunkies.com (American and Euro codes)
Action Replay Max is a new coding system they've brought out but has basicaly the same results.
You can either pay top whack for an AR Max card and CD or get a cheap AR2 card and CD (which will allow you to use hundreds of codes on from their site) then get the AR Max upgrade CD at a later date if you think it's necessary.
At the moment they are releasing codes for both versions but I guess they'll be phasing out the AR2 style of coding. I've used AR2 since getting my PS2 and have just recently purchased the £10 upgrade CD to turn it into an AR Max.
Both types also come with DVD X which should allow you to play DVD's from any region on your PS2 though I haven't had a chance to test this out.
