javeryh:
Anyone know why all of a sudden my P1 Start button thinks it is the Exit button all of a sudden? I can't play anything! Ugh... the computer in this thing sucks ass. I'm going to have to replace it and set everything up again. Need to get a cheap i5 from eBay or something but I don't feel like paying for it.

:banghead: :banghead: :banghead:

You may find that a keyboard tester program is useful for troubleshooting this issue.

1. Is there a short between the P1 Start and Exit input wires?
- Do a resistance/continuity check between those IPac inputs -- with power off, of course -- it should read as open/no continuity.

2. Was the Exit button (UI Cancel) remapped in the MAME "Input (general)--User Interface" menu?

3. Is P1 Start somehow triggering the P1 Start + P2 Start = Exit shifted function?
- Probably won't be a constant ground applied to P2 Start input due to the way shifted functions work.
- You can test this possibility by disconnecting the P2 Start wire at the IPac.
-- If P1 Start still behaves like the Exit button, you can eliminate shifted functions.
-- If P1 Start doesn't behave like the Exit button, there could be a short that triggers shifted functions.

I came across this build in my saved reddit posts that I was going through on a slow, holiday remote work day and came back and signed back in after 15 years to tell you how incredible this is. I really appreciate your threads and builds. I've read every post about this build and the twins for your family members.

I got into candy cabs and don't currently have a wood cab, but I really think I'm going to try something like this in the future. You are the man. A $100 optiplex would be a huge upgrade for sure. I see them/use them often.

Thanks for the tips. I will definitely start messing with things early this year now that I do not have any active projects on my plate.

So... this only happens like 1 out of every 10 times I boot the cabinet. It's so weird. I actually haven't troubleshooted yet because the cabinet is totally playable after a reboot if it doesn't work the first time. It also likes to periodically tell me that one of the computer fans is not connected and refuse to boot... but it is connected and this also only happens 1 out of every 10 times. It's annoying for sure so I think I just need to replace the PC at some point.

Thanks a lot for the kind words. I'm glad you like it - I probably make it seem 100x harder to build than it actually is because I'm not that smart and I overthink every little detail. You should definitely build one - these cabaret cabs are really fun and barely take up any space in the house. I love them. :cheers:

Aside from an intermittent short like Scott talks about above, the other issue I sometimes have with IPACs is when a short (or just someone pressing a button) occurs during either PC startup or re-programming the IPAC.

A short occurring during startup/reprogramming times can make the IPAC work weirdly, especially the shift function, or even not work at all. So, ensure *all* buttons are not shorted/pressed at those times.

IPACs use the LED for error reporting. When you turn everything on, observe the IPAC closely. The LED will blink a number of times: once (USB) or twice (PS2), then stays on, is good/normal. Any other behaviour indicates an error of some kind. If LED stays off it indicates an IPAC connection/driver issue. If the LED flashes 3+ times then it suggests a shorting problem: To narrow it down, count the flashes and refer to the table (near bottom of this page: https://www.arcadeworlduk.com/pages/IPAC-2-Code-Table.html).

EDIT: here is the same LED flashing error code table, but from an Ultimarc site. For some reason it was harder to find this link: http://www.ultimarc2.com/jpac2.html

I've found this to be very helpful for tracking down CP shorts.
