ExMx level recording if doom2.wad is loaded (Solved)

I'm not sure about this is the right place to write this.

Situation:

I have a wad, which have maps in ExMx format, but loads with doom2.wad. 

If I wanted to record it (e.g. E1M1), it failed at MAP00 not found, or started with MAP01.

How can I load the map with cmd?

Does it work if you use doom.wad as the iwad and doom2.wad as another pwad? 

Yeah, it worked. Thanks!

I've got the problem again, but now E1M0 instead of MAP00. (The intro level, I think)

Ok, I found the way to record it. I need to use recordmap in the console, due to the titlemap I can't record with cmd.

Thanks for the help.

-warp 1 1?

+map e1m1?
