Yeah, the non swgemu.com servers are just running old versions of Core1, which was the original work done on the project. We're up to Core 3 right now, which you can only find on our TCs.
Problem is that our lead member is really... touchy. I'm not gonna lie, the guy is a complete douche, he starts a ton of drama, and has made dozens of people quit the team over the years. The problem is that he's simply the best at sniffing the packets and doing the reverse engineering. The guy btw is Ultyma.
Yeah, he's incredibly hard to work with but it would be slower to go on without him than to kick him out, not that we could even if the rest of us wanted to. He owns the site and controls the donations so we're stuck, but we're doing the best we can.
Just two weekends ago we had a major stress test. We had 582 people in the Dantooine Mining Outpost with no lag, no disconnects, et cetera. Server ran smooth as glass even when we all started PvPing each other. It actually ran better than an SOE server did.
