I have another question, how do you launch to different levels in nxdoom, I found some mods that for some reason they start out as doom2 if you load them, but if you warp to level 1.0 "i'm using nxdoom pc" you will go to the first level in the mod. Is there a reason for this? Are these mods that don't require the doom2.wad? can you load nxdoom without using the doom2wad?
This is one of the wads that require you to warp ahead.
For this one it's level 2.9
I also noticed that wolfendoom astro3 you must warp to level 1.0. Any clue why that is?
