Simon: The first pSDL game

I created Simon the memory game for prizm using pSDL to show the basics of what it can currently do(I'm working on image loading and I may be able to finish before I leave tomorrow).
At the first menu heres what you can do
Press 1 to start it with text at the bottom for which arrow it maps to
press AC/ON to start without the help
press esc to exit

while it is running it will who each color/help if you enabled it for 3/4 of a second and then once all are shown it will go to black and you can start inputing arrows and the screen will change to the appropriate color
if you manage to get to 25 correct you win(the game)

My code is not exactly the best example of SDL code but here it is...

Spoiler for code:

EDIT: fixed error where esc could lock up calc
