quake console appearing, then demo and menu

[behind_you]

hey im not sure where this goes so im posting here. move it if necessary.

everytime i start quake, it shows the console then the demo play.

how can i make it so that a sprite or lmp is shown (loading), then instead of the demo playing, it shows another lmp? im sure it's source code i should be looking at but if its possible in quakec, that would be better.

when the menu shows up (singleplayer, multi, etc.) how do i make it so that an mp3 file plays? but how do i make it that when you pause, the game, it shows a different menu, and the mp3 background music volume is reduced?

thanks a million to all that have helped me so far!!!! ps im using proquake psp, so instructions tailored for proquake psp 4.7 is recommended
