Hello, About the colors, from what I've read, the Atari 2600 has 16 distinct colors, then a series of brightness levels it was like a total of 128 or something. The word HELLO is actually being drawn. Check out this in the code: PFData0 ;H 4 5 6 7 .byte $00,$f0,$00,$A0,$A0,$E0,$A0,$A0 PFData1 ;EL 7 6 5 4 3 2 1 0 .byte $00,$FF,$00,$77,$44,$64,$44,$74 PFData2 ;LO 0 1 2 3 4 5 6 7 .byte $00,$FF,$00,$EE,$A2,$A2,$A2,$E2 PFLColor ; Left side of screen .byte $00,$FF,$00,$22,$26,$2A,$2C,$2E PFRColor ; Right side of screen .byte $00,$1F,$00,$6E,$6C,$6A,$66,$62 Notice in registers: PFData0 is the H PFData1 is the EL etc. Then the colors are set in the PFLCOLOR registers. Since these are playfield graphics they are kind of backward and confusing, but hopefully this will give you a start. There is an application someone wrote caled MakeGraphics or something (I don't quite know where to get it.)... You can use it to replace the info in these registers and make the playfield say what you want. It will help you begin to understand what's going on. Good luck my friend. Joel D.

( i find my self proud of this ) . but ok i dont know where hes getting the words HELLO to show up on the screen also i dont see how the colors are done. like the series of colors able to be used . i know the PC has 256 how many does the 2600 have 8 ,16??? also do you know how the color is done? these are minor questions i still have also the major ones is wondering how to create walls within the field itself ( lets say i wanted a box within the boarders of the game COMBAT for instance. ) how would one go about programming it? ok please help thanks > > - > Archives (includes files) at http://www.biglist.com/lists/stella/archives/ > Unsub & more at http://www.biglist.com/lists/stella/ > - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
