I dropped the single/continuous fire done whith the player 2 difficulty switch and used it for the pal/ntsc conversion instead. Somebody might not like this, but this way I've recycled a lot of bytes. > But that leaves the question, what the problem was. > What exectly do you mean by removing one line? The screen kernel, from the top of the screen to the line after the 1-digit counter, is made of 178 lines. Then, there's a "filler" loop thad does 192-178 (or 228-178 for PAL) STA WSYNC's. With "removing one line" (not very correct indeed) I meant doing 191-178 lines instead 192-178. > Do you use any timer loops in your game, that don't start and end with a > STA Wsync? The two timer loops (one to wait for the end of Vblank, the other for Overscan), are like this: LF20C: LDA INTIM BNE LF20C STA WSYNC That is, there's not a STA WSYNC immediately before the start of the loop, but how could this matter..? > Didn't you say, that you have a modern multiple standard TV. Maybe that > one automaticly blows up too small images? Not at home, but I'm very curious to try the game on it. It's my girlfriend father's TV, and since I must go there with 1.an Atari 2600 2.power supply 3.cables 4.Supercharger 5.Mac Powerbook I need to find the good moment... :)) P. -- Archives updated once/day at http://www.biglist.com/lists/stella/archives/ Unsubscribing and other info at http://www.biglist.com/lists/stella/stella.html
