ive made a set of menu functions for dbclassic, all you have to do is set a background image with:
init_menu_bg(bgnumber,filename)
then set the buttons with:
init_menu_button(buttonnum,normalfile,rolloverfile,xposition,yposition,imgwidth,imgheight)
then inside a loop have:
do_menu()

sync

and you can also detect clicks with a rollover to run a function like:
if rollover(imagenumber) = 1 and mouseclick() = 1 then new_game()

hope i didnt screw up too badly

if you want to use it in your games then use it, you dont need to put in any credits unless you want to.
