I'm still not 100% Certain, but a couple of things, when I had the issue initially I had patched the Pi to the latest version, When I then Re-Imaged the SD, from a download 6-1-4 I believe, I then tried to turn on both Open JVS, and Power Save, and it did the same thing (I also didn't have the O-JVS hat attached) I then re-imaged the SD a third time, this time left it at default and was able to get the game to load / run, which was my objective as I wanted to check out a new CP for a game. So I haven't gone back and tried either of those options to see if the issue returns, and possibly I should try one at a time. To see if I can find out which or neither is causing this.
Also I'm powering the PI, through the header Pins, so that may also be part of the issue, but like I said it's been fine for years... and is running like that again... and was able to upload the game using the header pins for power.
It's a good San-Disk CF, and The Pi is working well for now, as it was able to upload the file to the Net-Dimm, what the underlying issue is at this point I can't say. If I find it, I'll comment and someone familiar with the code can possibly look at it and see if it's an actual bug, or just me turning things on (JVS) that I don't have installed yet.
I do want to turn on the Power Saver, as I typically only change games right on startup, and I have a battery backup attached to the Net-Dimm that keeps the ram powered for up to a week without ac power (Motorcycle Battery with a step down converter from 12v - 7.2v, and an trickle charger so it can run indefinitely, just not more than 5-6 days without any AC) So having the Pi is really only for changing games.
