I bought the retroid poket 2 too. My aim for buying it was to testing and playing insurgence on this device. So I tried it and have bad news.
First starting the game takes quite long but after waiting one minute it “runs”.
After starting the start sequence were the blond guy is talking to the publican the game runs very slow. But when you begin to play its ok it’s “playable”.
Now all is good I thought but there are two big problems.
First problem is that the controller of the retroid doesn’t work whit joi play or mby I don’t find the solution.
Second and the way bigger problem is that after saving and closing the game, the game doesn’t load if u want to start the game again.
Also if you start insurgence for the first time, the game opens an tells u if u willing to do changes on the settings, if u press yes the game shut down. After opening again the error massage "script ‘SpriteWindow’ line 1354 … " appears after pressing start or any button on the starting screen where the picture of the legendary pokemon is.
So to sum up it would be so nice to play the game on my retroid but it doesn’t work for me. Maybe there is a solution, I thought of a light version of the game (maybe someone done something like this) where there less special effects or something like that .
Pokemon insurgence works on my smartphone perfectly, so i think this problem has to do whit only the power of this device.
By the wau, I’m Austrian and my English isn’t the best so sorry for that
