How do you press 3 buttons or more

[Han Sik]

I'm using ppsspp on android.And I can't press 4
buttons at the same time.It's also difficult to
press triangle and X at the same time.Can you
guys please add the multikey features like in FPSE?
To combine the square and circle,triangle and X,
L and R,three buttons,four buttons,etc,we really really needed.
If you do,tekken players would be happy.I'll be
waiting for the multikey features on the next
version,sorry for my English.
Thank you,PPSSPP Team :-) :-)
