Do all wireless controllers work with Graal?

I was looking into buying this, but I don't wanna buy something that wouldn't work for all or most of my games.

For graal? You'd have to root your phone, or use a keyremapper to change your controller to the controls the pc has, so S would be your slash, a for grab, d and f for your items, etc. Though sometimes it would freeze out, or the app would crash.

iOS, Try to buy one with a holder for your phone or tablet.

Android controllers won't work with graal. App would just crash, after a few mins.

there were a lot of YouTube videos where the 8bitdo controllers were reviewed, and they worked fine with no problems.

this one was on iOS

 

Just hack your 3DS, get 3DS Controller, and play on PC lool.

PC is the best platform when it comes to controller usage.  

pls help
