So recently I've been playing lots of super smash bros melee on my phone since the recent builds maintain fps above 23
anyways I decided to redownload the sixaxis controller app and dust off my ps3 controller(I play more xbox/pc) and I noticed a couple of things the L/R buttons don't work in game(ssbm is the only one I'm currently playing until this is fixed) I thought it only didn't work on the touchscreens but was proven wrong and then there's the c stick which the up/down don't work and the left/right are inverted(although this can be fixed by mapping them to there opposite sides) I was just wondering if this a bug which is known/being worked on or it's a problem with my device maybe or something related(I know it's not the ps3 controller I dusted off the ps3 and tried it and everything was working fine? My final question can we actually use two controllers on android I tried playing by using touchscreen and then just enabling the second controller 2 and mapping it but it wouldn't do anything?
