Confused about versions 1.4, 2.02, 2.2, 2.31 Where are they

I cannot locate a download area or similar where I can find and try the various firmware versions. I hear that the latest, 2.31, has some issues with glitching and transparency, and that 2.02 might be better. I cannot find 2.02. I have 1.something now and it’s stable but want to upgrade, if possible.
It would be good to have a download tab and a list of the versions, with descriptions of the pluses and minuses of each one. Is there such an area?

Thanks! Irv

Hi Irv:

We wish to have a clear complete firmware list, but not having resource to work on that yet. I have uploaded the default v2.02 one here: … u&can=2&q=
