| Werid Scrolling Effect on Vertical shooters? |
| << < (2/2) |
| TOK:
I've noticed a scrolling effect similar to that description in Xevious. Doesn't seem to be as pronounced as the problem you're experiencing, but noticeable enough that it came to mind as soon as I read your message. I haven't caught it in other games, and wondered if it was the way Xevious actually scrolled. Doesn't seem as smooth as I remembered it, but its been over a year since I've played a "real" Xevious. |

For games like xevious & R-type, you need triplebuffer off (triplebuffer 0). But on some like Wonderboy, you must run it on or the game is unplayable (for me). Other thing it could be is the h/ware acceleration from your video cards. Some have a problem with the way they tile images on the screen, which could be what you are looking at :dunno You can try looking at your video card settings. Need more data! video card, software, ini files etc .... |

Ok more info, im using an AGP AvrcadeVGA card, and using Directdraw rather than Direct 3D, (as this is the way your surpossed to setup mame to use the ArcadeVGA card). No hardware stretching or triplebuffe. Ill try and get some picks later but not sure if it will show that well in stills need to be moving to notice it i guess. Have also notice it in Undercover cops, when your character moves across the screen looks like the same effect. A good thing to compare it to is the Mode 7 effect that the Genesis/Megadrive try to do in the last few years of its production, manly in contra Hard Corps, the mid level boss on the 1st level kind of has the same effect on him, guess this will only be useful to people who have actuall played this game or had a MD or Genesis |

Ok think ive pin pointed the problem, if you press the '`' button when a rom is playing which brings up the volume control, you can scroll down and changed the picture, one of the options for stretch horizontal was changed from the default setting, i changed it back and it stop the scrolling problem, only think is now the game display is seriously overscanned :banghead:. Cant understand why stretching the picture would cause a scrolling problem :dunno |

MODE 7 was the SNES's background scaling and rotation mode! Read my post above! Perhaps you're talking about PARALLAX scrolling where the screen is split into different strips horizontally, scrolling at different speeds??? |
