i've noticed on my satan's hollow that you get 'snow' when it switches from attract mode to starting the game, i.e., where the screen would normally be blank there's a screen of multi colored snow.

also, during attract mode on the satan's hollow flaming letters, when the first o in hollow writes a small part of the flame is out and it (the little flaming pixel) shows up in the red copyright lettering below.

everyhthing plays fine, and i've noticed similar posts to this on the weird mcr graphics glitches. is this basically the same thing? that's what i'm assuming.

Try swapping out the 82S09/93419(??) RAM chip on the CPU board. If that doesn't do it, try the Z80CTC on the same board... That doesn't do it, try the video RAM on the VidGen board. This last one is the least likely, but I have seen all three of these failures cause these symptoms you're describing. Obviously, check the interconnect cables, too. Those things cause wacky problems across the board!

now is this similar to the occasional random red pixels and stuff you see on the right side of the game, which i've noticed in other satan's hollows, which i've heard is just that normal glitch? anyone else noticed it on theirs?
 
Yeah, I've noticed it on mine. I think mine is the first "o" also. I haven't bothered to try fixing it. But I at least know what to look for now. :)

maybe it's just part of that mcr glitch, cause i was just looking at a video of a tron cab (not mame) playing on youtube, and it does all the same stuff pretty much.
 
I've never seen the snow on my upright. And the title screen problem doesn't show up on my cocktail. Nor did I see it on "Lucifer's Upright" at CAX this year.

BTW, who actually owns that Satan's Hollow upright? I wanted to ask where they got the freeplay kit. Whoever owns it...that's awesome. Plus: Best. Owner's tag. Ever! Wish I had a picture to share with folks who didn't see it.
 
that tron defenitely has some video issues. The sides of the MCP cone should be solid, not dots. They all have a bit of snow between screens, but its usually just white and much more sparse.
 
who knows. i've seen that type of snow on all the trons i've played, as far as i remember, anyways. (which is saying a lot...) :p
 
ok, so i went and booted my tron just to see- it does have that snow (what i get for speaking before i look). But, there is definitely a graphics issue (or a cam issue) the mcp cone side walls should be solid.
As far as snow goes, its normal between screens on most mcr games, but its very fast. Its much more noticable in the video than it is on the actual game.
I think it varies from game to game. Its also fairly common for there to be some garbage on one side, the monitor is normally adjusted until its off the screen. Not sure specifically about SH, but i know Spy hunter has it, and i think tron, too. If it doesn't bother you and the game plays ok, i'd just leave it.
 
Ok, now I know what you're talking about. I just checked and my upright has "snow". I agree that that's normal.

I also confirmed that it's the "H" in the title screen that has the displaced pixels, not the "o".
