The PSp Slim Serial (or Remote) keyboard hardware may making.
But (Pikey) have the software support..........
Needs the software support!!!!
Let me rephrase guys...
SIO
is that mic port like you said. It's all possible and the PRX plugin still exists -
piKeySIO.PRX.
It all works great, it's just an M33 issue. After Dark_AleX adds it to the resolver it should work.
Also, I noticed on PS2Dev forums another guy working on it, so hopefully it should be up and running soon, but please...
DON't ASK!!!
