Starting with Player 2 In A Single Player Mode

[maxman]

Everytime I try using single 1 or maxplayers 1 in levels.txt, it does not allow player 2 to start the game in the select screen, let alone player 1. Do I need to use "nojoin" variant to stop player 1 from joining if I go with player 2 solo?

If I understand correctly I think the nojoin is a good choice, I'm using it in the Survival mode for SORX where it doesn't allow other players to join in-game.
You can control it by changing the available credits too at certain moments.
