So I was the only one waiting to play ITG2 after the obligatory guy with the ponytail who's there everyday. He finished up his 15 footer and as me and my 8 year old sister were stepping up, he UNPLUGGED the machine. WTF was the point of that, was he just being um, mean? I've played with him before a while back, he knows I'm good, but I don't know what this was. We had to wait for it to boot up again and everything. Did something need to be resetted or what?
It's not a big deal or anything, but a little curious, I don't go to the arcade that often anymore.

As ITG machines stay on for longer, they take longer and longer to read USB's and occasionally don't read them at all. Maybe he was having trouble getting his USB to read fast, so he unplugged for the times being. It's good to restart ITG machines every once in awhile.

| I think the pads get less sensitive too. |

How on earth would rebooting the machine fix that? >.>

15 footer?

I don't know. I've just heard that they get less sensitive the longer its on. |

The R5 and R8 patches have a major bug in them. They added a "debounce input" feature that was supposed to cut down on pad misses by throwing out what it considered spurious signals. It was implemented so aggressively/poorly that in R5 it considered a coin insert signal recieved during a loading screen to be spurious and thus ignored it. R8 was released two weeks after R5 to fix the coin eating issue.
I can only assume that the patch must keep a record of signal strengths in RAM and use this to determine whether or not to throw out input. I step lightly and seem to get the majority of pad shutdowns when compared to others who step more heavily than I do. Every time a pad stops responding at my local arcade, a simple reboot is all it takes to get it working again. |

That's interesting. I wouldn't have thought there would be that kind of logic involved in filtering inputs, but as far as "signal strength", I doubt it. They may be better switches than the DDR switches, but I doubt they're analog - they're probably just digital mercury switches like in DDR, but with a better sheath that's more resistant to deformation and rotting. If there is input filtering being done, it'd probably be removing what are deemed to be "intermittent" signals by looking for input signals that rapidly phase from on/off. Which would affect light steppers, probably.

All circuits are analog, so-called digital circuits just aren't as picky with their input <g>. Though you're probably correct in assuming that the pads are treated digitally seeing as they connect through a JAMMA connector.

This is on upgraded cabinet, so the switches are probably still the original Konami ones. On a side note, did they actually use mercury switches in cabinets?

Yeah, that seems like it would be the more likely scenario. |

This is my theory.
System573 is JAMMA to begin with, so it doesn't have to go through an I/O JAMMA to USB converter; thus, the reason why DDR doesn't suffer from the same problems as ITG upgrades. The logic chips on the ITG-I/O unable to handle the noise coming through the pad's wires cause it to have the issues it does. USB + linux = not much fun, as seen when noise causes the sensors to fail, it goes completely out most of the time. The patches seem to fix this for the most part, but explains why reboots are necessary.
This is just speculation from someone on the outside.

Yeah, I had Digital Devices.  I know about the logic thresholds on switching components and such. I meant the actual behavior of the switch, as opposed to having a sensor behind it.
