Forgive me for asking so many questions, but you guys explain things so much clearer than the Stella manual. So I would start the program with: LDA #$02 Because this hex number, when tranlated to binary, is 00000010 and bit 1 at memory location $0000 starts VSYNC, and I next: STA $0000 Once that is done, I can put a couple of commands in, to blank out some memory or something. After a few commands, I would: WSYNC Then I can put a couple of other things here if I want, or just leave it blank and immediately: WSYNC Then I do whatever it was again and: WSYNC That will make the third scanline for the VSYNC. I then: LDA #$00 STA $0000 Which turns off the VSYNC and then I start working on the VBLANK area, right? (Not to repeat everything gentlben wrote, I just want to make sure I have the logic right.) So VBLANK just sends out whatever color is in the background register at that time, huh? Could come in very handy. > no, not this time <gets the tranquilizer dars> I'll have you know if you shoot me with a drugged dart, I'll...well, I'll be very happy, but that's beside the point! ;-) _________________________________________________________ Do You Yahoo!?
