Hi,

I am learning assembly programming 16 bit. I would like to code the game breakout ( a very simple version ) using it and would like to output messages straight to the video memory, that means i wouldnt use interrupts to output stuff. So far I have this much code. Anyone have any suggestions, tips or maybe even a link to source code that can help me out ??

Code:
.model small

.586

.stack 100h

.nolist

	;*************************************************

	;Includes

	;*************************************************

	include bios.inc

    include constants.inc

.list

.data



.code



	main proc

		.startup

			@Cls

			@Setcsrpos,0,0



                        mov ax,0B800h

                        mov es,ax

                        mov cx,2

                        mov ax, 0Fdbh

                       Loop1:

                        mov bx,cx

                        ;mov ax,002Dh

                        mov es:[bx],ax

                        add cx,2

                        cmp cx,78

                        jng Loop1



			;initialize everything

		;@@:

			;get user input



			;update paddle



			;update ball



			;draw the screen



			;check if all bricks are gone, if so then quit

			;jmp @b

		;done:



           ; @Cls

           ; @Setcsrpos,0,0

		.exit

	main endp



end
