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: http://mametesters.org/view.php?id=4082.
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.

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.

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.

I need to say that perhaps not is a bad rom dump and also not is bug in atarig1 core.
That problem happen in others games exactly in a similar way randomly since before 2012.
The background tile map randomly flickering in others games for example Street Fighter 2 Hyper Fighting in E.Honda, Ken and Dhalsim stages.
I will try make video capture and after I post the result here.

This is not true, you do not have a real PCB to observe its behavior, I do. In the real PCB this glitch does not occur 100% of the times I boot it up. This glitch occurs in the very 1st loop in MAME all the time, while in my PCB, the 1st loop is perfect all the time. The glitch happens randomically in MAME only, not in the real PCB. You cannot compare it to other games, saying this is common place in 80% of the games of that era or whatnot.

Another bug that proves that this driver is not 100% accurate are the vertical gaps in the backgrounds. MAME displays larger vertical gaps while in the real pcb the gaps are almost inexistent, this is proven in several pcb videos on Youtube, mentioned in this specific report already opened here.

An reply before of my reply say that not is bad rom dump. Thus I had remembered that others games also has the same glitch.
Yes have others games where flickering the tile map in background similar how is saying in that issue.
"Compare" can show that is perhaps an bug in video core, other core or even atarig1 driver.
Have an exact same glitch happening in others games, but is random and not all time how is reported in Pit-Fighter.
I will try play SF2HJ and post here an video capture and thus being an random bug not will be soon to post;

Yes the atarig1 has problems.

I had posted in
https://mametesters.org/view.php?id=7680
the revision 1 is using an date after of revision 9 only to say that perhaps revision 1 not is exactly revision 1.
Your reply was right, but the report was closed.
Acknowledged status is better than close that report because is for try figure what is the exact revision number of revision 1.

Have an other report in
https://mametesters.org/view.php?id=7681
where have input delay in revisions 1, 6, 7 and 9.
You say that had happened changes in gameplay between revisions. You known the glicth where Kato does an 100 % combo ? If yes was removed after of revision 5 ? In MAME in revisions 1, 6, 7 and 9 not is possible to do Kato 100 % combo.

If you want to believe that and still want to compare oranges to apples, go ahead. I won't reply it any further because it's useless information anyway.

[Quote:Augusto]Yes the atarig1 has problems.[/Quote]

Well, it seems to be the only point where we will agree here...

To your information, there's no "revision 1". All dedicated machines were delivered with revision 2 onwards in them. The 2 player version (dumped by me BTW - ask Smitdogg if you want) is a later version, thus it's more like a revision 10 than 1. Please do better research before posting dude! Closed reports are stored anyway. So if you want to have your useless (with all due respect) information stored, you got it.

Yes, I did several videos on Youtube (search for ChipsFoose channel - that's me ;) ) finishing the game with 1 single credit in all difficulty levels with all characters and also showing Kato's infinite combo and many other things other players never did on video before me. So yes, I'm a Pit-Fighter f****** expert and I know which bugs were removed in any of the versions of this game. I even talked to its creator, Gary Stark, who confirmed several of my information before posting things here. So, again, do better research before flooding useless information here.

And if you want to go ahead with this, please, let's do it out of here. Find another forum where you want to discuss any aspect of this game and I will tell you every thing I know about it. End.

Yes has others games having similar bug how are being in Pit-Fighter.
My act was try add that information, but NOT say that atarig1 not has bugs.

About my report about revision 1 with strange BIOS date also was to add information because searching in mamtesters.org not has any issue about it.
Thus being look how revision 1 is 10 how you are saying.
Any way that information in "revision 1" need to be fixed that was the because of my report.

Yes has more input delay in revision 1, 6, 7 and 9 than in others revisions.
I asked about if was removed Kato's infinite combo to see if has any detail related with input delay. Not exactly about gameplay.
Even thus using input twice forward or back has delay if comparing with first revisions.

Your post is correct about that game that is unhappily underrated for several gamers simply because is only 1 life and not refill energy.

I use OSD values for debug.
Overclock 68000 to 101 % not happen the gfx glitch bug.
Verified in all sets not happening the bug.

Need to test if the vertical gaps bug also is "fixed" if overclocking the 68000.
