I went back to the Acho C901 firmware upgrade and added the 10.1 flash player and plugin that I found for Android 1.5 users.
What I have is an interesting beast. It plays some things like games such as Wave Blazer Lite and Tiki Towers. I believe these use flash to a certain extent. I know that Wave Blazer Lite would work before but, choppy as all get out. Now it plays smoothly and fluidly I was quite amazed. I was trying to find an older version of Angry Birds but they seem to have all gone away or wont install "On this phone"
But it opens up some interesting possibilities for the RockTab. At least makes it open to more things to run on it than it is from stock.
It's not perfect but it's almost as good as the 2.1 firmware. Not to mention much more stable.
