Hey, I managed to connect my PAL Dreamcast online with DreamPi and I wanted to play on Schtserver. I'm using a burned CDI of PSO V2 USA.
I've changed the DNS in the internet settings to the one present in the homepage, but I keep connecting to Sylverant Server.
Reading the guide on how to connect I've read that you need a codebreaker or boot disc to be able to connect, but then I noticed at the top of the page that now you can simply use the DNS without patches, and I'm a little confused on how to proceed.

Any suggestions on how to connect?

The codebreaker is not needed anymore, also if you go strait to silverant it's because you have one of their modded ISO that have their server address coded in it.

All you have to do is to point your DNS setting to the server IP. If it's not working that mean your router or ISP is intercepting the request and answering to it (so pointing you to Sylverant)

If this is the case you can host your own MrDNS server locally and have it respond with the server IP

So the DNS metod should now work even with an NTSC copy of the game, right?

Yes, i know some player is also using the same disk as you.
