Just got my new Retron 77...I updated with the latest Stella release (6.4.0). Sadly, my 2 favorite games (Montezuma's Revenge & Tutankham) do NOT play. Paddles are jittery with Astroblast and Circus Atari. Guess there is no use even buying homebrew games like Spacerocks, Scramble, and Galaga.
sucks
