VKB-SIM

I was looking to update the firmware on my my NXT gladiators but am not which of the options I should use ( I am using Gladiator NXT Space Combat Premium, bought start of the year and on version 2.080). Under Gladiator_NXT_series there are two options.

_Gladiator_NXT_OTA_v2_12_2
and
_Gladiator_NXT_v2_v2_12_2

I don't see anything indicating which one I should use or how those two differ. I also thought I read elsewhere that there are different selections for right vs left, so wanted to make sure I am not missing something. Appreciate the help!

The OTA firmware is for Gladiator NXTs equipped with the omni throttle extension. But I'd suggest to wait a bit longer on updating the firmware, there are some small issues currently; a patch will come soon.
