ZDL and Hamachi multiplayer issues

Post by Skebblors »

Hello, I hope you are all doing well, wherever you may be. I have a technical issue regarding multiplayer Doom using ZDL, Hamachi, GZDoom, our mods or any configuration thereof. Buckle up, it's a long one.

Some friends and I are dead-set on playing 3-player co-op Doom using Hideous Destructor. As an aside, we want to play a megawad called Going Down, which looks supremely cool. We're trying to connect using Hamachi, and we're also using ZDL to point to our respective doom2 IWADs, the Hideous Destructor .zip and the Going Down .wad file. Our ZDL setups also point to GZDoom as a source port/engine. We then use ZDL to join a host IP for multiplayer.

This has worked for my friends, and they've been able to play co-op 2-player sessions extensively. The first time I got everything installed and setup, I was able to join my friend hosting as well, and we could get into a 2-player game no problem. However, attempts to host and join a 3-player co-op game have returned the following:

1. At first, the two joining players (myself and another) would connect without a hitch, but the Doom game window would pop up returning just a black screen and playing music. Nothing else happened, and quitting was the only option.
2. Eventually, after we tried re-jigging and updating versions blindly (probably where we went wrong) only the other player was able to join the host. I can no longer join, and I even cause my friend's ZDL window to deliver error messages which simply state "Execution could not continue." followed by "PreGet: ECONNRESET". This now happens consistently when I try to join his hosted game.

Our setup is as follows:

1. Switch on Hamachi and set up all our IPs. We've seen somewhere that using Hamachi IP aliases is suitable - in fact, it's the only time it has ever worked for us.
2. Open up ZDL - my friend hosts and has it set to 3 players. We join using his IP. The ZDL log usually returns our player names and seems to confirm a valid connection, but now it returns the aforementioned error messages in the ZDL log.
3. We either get a black game window, or I don't connect at all.

We did try using Zandronum and Doomseeker, to no avail. We've gone through various bits of documentation and various forum posts, and these have also been of limited relevance to us, it seems.

I'm not the most computer-literate person and much of this is alien to me. Even using ZDL has been a learning experience, and Hamachi I simply don't understand at all. I feel that if I can find a way to understand what's going on, then my more techy friends can understand it too.

If I haven't mentioned something important please let me know and I'll try to follow up on everything. Thanks and hope you all have a great weekend.
