First I have the free version of chainfire and other games such as Galaxy on Fire and Samurai 2 Vengeance THD work fine on my Dropad, so could you explain the reason for having chainfire pro?Most time its the setup file its not supporting our device
you must have the one for samsung and sometime for
For motorola that solved the problem for me
Other issues could be you must have chainfire pro
As for your second reasoning, games for windows work on all windows capable computers. How come vendors create different versions of games depending on phone/tablet brand - this is getting ridiculous.
