Here is a simple step by step guide for playing your games online.

First and foremost, 32bit users will need to get WinPcap from HERE

1. Rip your cd/dvd to iso format! (very important) And the Network Access Disc if you have it.
2. Burn the Disc ID Util CD Version to CD or Disc ID Util DVD Version to DVD and run it on your PS2 (using tricks described in the BIOS dumping guides)
3. Insert your game disc and press X, Read off your Disc ID, this is your DNAS code. You might want to read your Network Access Disc Disc ID too, so you can complete the setup.
4. Run WinDIP, select your iso, press the scan file, then verify version.
5. Enter your Disc ID in to the 5 boxes.
6. Hit patch
6.5. Repeat 4-6 with your Network Access Disc.
7. Next you will need run the Network Access Disc, or some means of making your network config, some games might work, but some will just show garbage, so this is the best option. All network adapters and slim PS2's come with one. DHCP doesnt work, so hard code your IP addresses. You can either run this on your PS2 and transfer over your NETCONF files to a PCSX2 memcard, or run it on PCSX2 directly.
8. Run your ISO and have fun playing online

Note: when you configure the dev9 plugin, tick the ethernet mode, switched mode will work if your ethernet card supports promiscuous mode, otherwise you need to use Bridged, which should be more compatable.

Important Note: If you get DNAS errors -880 or -881, copy your bios back over from the dump, deleting anything in your PCSX2 BIOS folder first, then check the file names! The new dumper tends to put the CRC in the filename, so when PCSX2 reads your BIOS it cannot find the NVM file (which you need for your MAC address) so make sure they have exactly the same name and you arent using a blank file made by PCSX2!


Any other methods discovered or explained on the forums, posts will be edited and forums will be given. This is the closest thing to legal you are going to get, any other method will be considered highly illegal, especially if it involves getting your DiscID from somewhere other than your disc.
