Thanks for the info.
However, I've found topics with some of these android consoles where they say that the most current remote play apk just force closes at start, so knowing which ones work is good.
Also, need the gamepad to work as the controller rather than the workaround, so knowing which of these android gamepad consoles work as controllers would also be good. Unfortunately, many people still have problems with getting controls sorted out, so it's hard to tell what will work, and this is crucial to my eventual purchase decision.
I'm particularly interested in the ipega products because of the sticks and L2/R2 triggers. But if there are other similar devices, that work better, I will look into them.
