Summary 00378: all pitfight sets: During the TY intro sequence, it shows a fast 'flash' gfx glitch that seems to be a bad rom dump or something.
Description A graphic glitch occurs during the TY intro sequence. It shows a fast 'flash' gfx glitch that seems to be a bad rom dump.

UPDATE (12/18/2011): According to the video posted by Smitdogg from Pit-Fighter Rev. 5 original PCB running attract mode/gameplay, the MAME romset has a graphic issue from a bad dump. Here's the link to the original PCB video showing no issues during attract mode:
Steps To Reproduce Just run the game and let it go through the attract mode for a couple of loops. You will be able to see the graphic glitch at ty's training sequence.
Additional Information Verified against a video posted by Smitdogg running an original rev. 5 Pit-Fighter PCB that shows no graphic glitches during attract mode. Video posted at bug ID 04082.
Flags Verified with Original
Regression Version
Affected Sets / Systems all pitfight sets

I see this consistently on all pitfight sets. It looks like a legitimate game bug to me, but it needs verification.

My setup is still a WIP and I can only get grey scale for some games but I made a video of Pit Fighter. This one is even extra funky, colors come in and out in one part... It probably doesn't satisfy the question. I can make another video in a few weeks when I can get color on this game, but FWIW:

I got this PCB working correctly with color. It looks like it's just rough transitions like lots of arcade games had. I'll upload a color reference video soon.

I'm curious why certain things were changed in this bug report rcoltrane. The version number is the version this bug was found in, not the latest version the bug exists in.

Also if it happens every time the attract gets to Ty's it shows the graphic glitch, that reproducability is set to 'always' not random. Lastly, no new information was atually added at all, except to add Smitdogg's info from a year ago to the description.

In short, this seems like a bug report that was just randomly altered to push it up onto the 'last modified' listing.

I reverted the version number and some insignificant fields.

Ok here's my attemp. I did this video using a Vogatek MK II supergun connected to my original 3 player Pit-Fighter Rev.3 PCB connected to a Samsung LCD HDTV through an S-Video cable. My TV is having some difficulties with the weird pcb sync frequency but the video is useful to demonstrate that the 'rough transition' does not happen on the real hardware and thus this is in fact an emulation bug.

Here's the link to the video on Youtube:

I guess this could be a bad gfx rom dump because it's an old set and I don't know if the 3-dumps-in-a-row rule was being applied at that time.

it's not going to be a bad dump.

also videos of games that aren't recorded at 60fps are useless for verifying this kind of single frame glitch behaviour.
