Summary 07833: ghoshunt, mouseatk, tickee, tutstomb: Random chance of launching with missing colors
Description These 4 games randomly load with incorrect colors. They appear to be missing red.
Steps To Reproduce Make a clean test install of 0.226 or 0.227.
Launch any of these four games.
If they load with correct colors, exit and launch them again from the UI or with shift + F3.
I have noticed that you must release the shift key to get the correct hard reset.
Sometimes they load with missing colors on the first try, sometimes it takes 10 or more times.
Additional Information Deleting nvram folders seems to have no affect on the % chance of missing colors.
I have had them load with missing colors on the first try before the nvram was created and I have had them load correctly a dozen times, then switch to bad colors, then switch back to correct colors on subsequent tries. This can happen from the command line, the UI, or Shift + F3.
I was unable to reproduce this issue with 0.225 or earlier.
Mallet Madness & Rapid Fire seem not to be affected.
Attached example snaps.

I did see this in testing and mentioned it, but it was random/inconsistently happening.
More than likely something requiring initialization is missing.

tickee was the only one to misbehave for me, being blue and black.

After the patch, it's working, but these days one can never be sure if a bug is truly fixed.

In my testing they seem corrected.
If they happen to regress again during the next dev period, I will re-open
