How to play PS2 games on my PC?

You need one of http://www.lik-sang.com/list.php?nav=over&category=219 to put your PS2 games on a VGA monitor. If you want to keep using your computer with the monitor you might want to invest in a VGA switch box too.

Keep in mind that the average TV's resolution is much lower than the average monitor and, as a result, PS2 games played on a monitor will look fairly awful (considering they are designed with that lower resolution in mind.) This is the same reason that trying to use a television as a computer monitor http://www.mycableshop.com/techarticles/tvmonitor.htm.

How fast is your computer?

AMD XP 3200+ with 2x512Mb RAM (nForce2 mobo) and about 80gb free on the hd. I have a DVD-R to keep space free on it. I have a shuttle case so I actually hook it up to my telly every so often.. (I have a Radeon 9600 pro with svideo out). I don't actually mind playing in a window (can you do that?) and it'll be PAL (I'm in the UK).

you need the http://www.jandaman.com/ps2vgabox.shtml. I have it and it works great. The only problem is, as mentioned above, the res is waay high on a monitor and leaves something to be desired on certain games, usually only on psx games tho.

Get http://www.lik-sang.com/info.php?category=219&products_id=274&, I have it and it works great, and I believe it's the newer version of what bob has. (From the picture it looks that way anyway)

That machine you mentioned would emulate PS2 games nicely. Get a controller adapter (PS2-USB) for less than 25 bucks and you have instant backups and easy playability, not to mention you can turn AA and AF on in the games. I cannot find a link for it, maybe its worth asking another Askme question on where to get one.

that looks pretty nice, banished. but whats "New YPsPr mode (for PS2 only)". that's the only thing the old one doesn't have...i think, since i dont' know what it is and it says "new"

Re: Keyser's note: PS2 games aren't playble on emulators yet. They're still in a larval state. PS1 games, on the other hand, are well-emulated, but emulator settings can be screwy and need to be changed between games, and some still don't work at all.
