Thanks to notthematrix and teslaman for their earlier posts about how to re-flash my Neptune controller.

I used a recovery SD to flash to RC6. Should I now upgrade to 1.06s?

What is the difference between RC6 and 1.06s? Is RC6 the initial version of the firmware (I seem to remember seeing RC6 when I first got my Neptune, before they came out with 1.00).
