Ok so like the topic reads I would love to learn how to make menu's for my game at least so i can start with that...

I wich to make a menu something like the Megaman X Maverick hunter for the psp is there anything you ways could tell me to read that could help me do it?
and I would really love to do 1 minute timeout to show a video of the game, like almost every game has when you just wait a little in the menu without doing anything of course I'll leave this for way later but I would like to have a reply here so I can check it up when I'm ready for such an implementation...

Thanks.

every game has (or should have) videos
developer logo video, publisher logo video
Intro
Cutscenes
and more

but it seems that currently there is no real easy solution for playing video, see other threads about video playback
its a sad story

I'm not familiar with the mega man game, so I have no advice on how to make that menu.

However, with a "demo", like ReBirth said, you make the game have states.

One state would be the menu--it listens for user input, and if no input is received in a certain time limit, the state changes to the play demo state.

play demo state: plays the game normally, but with a script or AI or something to control the player's character. If any user input or timeout, change state to menu state.

Of course, this all implies there are two states for game play: normal, where the user controls the character, and demo, where the computer controls the character. So, you can use the same code for gameplay and demo states, but have player/computer control character controlled by what state the program is in.
