I don't know if there already was a topic about that, in that case I'm sorry. Anyway, I'm thinking about changing the D-pads of my gba and gba sp with analog sticks. I know the signal will still be digital (also every game was developed with that concept in mind) but I want a better feel in my hands and I want (when I'll be more capable with c++, hopefully next year) to develop gba games that will use the analog stick better. Has anyone tried to do this? I'm considering the psp's stick, IMO it has the right size.
