Just a little heads up,
Adding the -fast parameter is completely redundant when playing on skill 5. It makes literally no difference as skill 5 already has -fast forced on.
The -warp parameter is incorrectly set to "-warp e1m1" instead of "-warp 1 1". So the game gets confused and sends you to e1m9. However, using "-warp 1 1" is redundant in this case because using the -skill parameter already warps you to the first level of the game.
