So I made a couple maps back in 2013 but haven't done any since. Kinda quit playing doom since then too. Anyway I enjoy zdaemon and zandronum both for different reasons and would like to make my map look good on zandronum but also work on good ol zdaemon (exactly like Romero's new Sigil). In fact that's the style of mapping I enjoy and will probably make something similar for fun.

1. Is chubz still the go to for learning how to map (i'm rusty as hell) and will his tutorials allow for the map to work in both zdaemon and zand?

2.What do I pick for "game configuration" in doombuilder 2 so my wad will be compatible in both zdaemona and zand? Do I just pick Doom 2 or Boom or what? example: teleports or traps working for one port but not the other etc...

3. Hell, is doombuilder not event he go to anymore?

4.Am I missing anything important to look out for that will prevent my wad from working on both multiplayer ports before I get started? Thanks
