NIAD Posted February 16, 2015 Share Posted February 16, 2015 You've seen enough. PM en route. My son had that game up until recently when we donated it along with numeous other toys to the Salvation Army. He never got very far without looking at the answers or relying on me for help. Good choice 5-11under. Quote Link to comment Share on other sites More sharing options...
youki Posted February 17, 2015 Share Posted February 17, 2015 for(aa=0;aa<256;aa++) {change_multicolor(aa,COLOR1+aa*;} what does that row? If behind change_multicolor there are calls to VDP (and at least 255 here) . ... i'm almost sure a NMI will occurs while you are accessing the VDP. In addition the change_spattern you do before and after are accessing VDP as well. ( i had lot of issues with change_spattern in one of my project...).

I don't have my code here at the moment, but I'm pretty sure I have nmi disabled at that point. Quote Link to comment Share on other sites More sharing options...

As i said here : http://atariage.com/forums/topic/230599-galaga-crashing-all-the-time/?p=3178975 The disable nmi don't prevent the problem to occur. if you are accessing the VDP when the hardware Interrupt Occurs , you can have glitches. And i think during the time of your loop , it could occurs. Quote Link to comment Share on other sites More sharing options...

And i think during the time of your loop , it could occurs. Well, I'm writing the colour of the characters here, and I need to do that, so I'm not sure what other method is to be used. I've tried to do it with faster methods with no success, although even faster methods would still have the same problem you're describing. Anyway, I'm not seeing any issues in the initialization stage. What I was seeing before I put the update-sprites command in the nmi (and nowhere else) was that some of the characters would be written over by sprite data and possibly other garbage after playing for a few minutes or so.

parkfun101 Posted February 17, 2015 Share Posted February 17, 2015 So, in terms of fewer or no nmi glitches, would you say putting commands like update_sprites, vram updates, etc. into the nmi be the best solution? I'm thinking I want to start doing that if it seems to be less problematic. Quote Link to comment Share on other sites More sharing options...

I'm thinking I want to start doing that if it seems to be less problematic. After playing some more, it looks like the problem remains for this game. For previous games, I've put all the "action" within the nmi, without issue. It looks like some others are doing the opposite. Whichever works, I guess.

Kiwi Posted February 18, 2015 Share Posted February 18, 2015 (edited) You can try slowing the color drawing down with this for loop with delay(1) in it. In the example, it'll change 32 colors a frame. This one method I would try. b=0; for(aa=0;aa<256;aa++) { change_multicolor(aa,COLOR1+aa*8); b++; if(b==32){delay(1);b=0;} } Hopes that helps a bit. The vdp seems to accept 200-300 bytes a frame. Edited February 18, 2015 by Kiwi Quote Link to comment Share on other sites More sharing options...

For me yes, but you have to be sure that what you put in the nmi() doesn't overrun the nmi. all what you put here should take a little less than 16ms . So just put here code that make vdp calls. Use the nmi method as a "rendering" method only , and put the logic of the game outside. Quote Link to comment Share on other sites More sharing options...

+5-11under Posted February 18, 2015 Share Posted February 18, 2015 Thanks for the hints everyone! As mentioned, the initial set-up is working fine. However, I'll see if there are other times the VDP is too busy. Quote Link to comment Share on other sites More sharing options...
