The idea of it sounds frustrating, yes. But I'm a big MUD player and I've been trying to think of a decent way to adapt a MUD client to the PSP.
Most MUDs accept N, W, S, and E as directions, perhaps the directional stick could be used as a navigation. I mean, look how heavy IRC is with the keyboard and it was ported to the PSP via a web browser. However, I'm not talking a web browser client.
I'm no stranger to coding, but I haven't coded much on the PSP. Wondering if anyone can lend helpful ideas as to how to first port a successful layout, or maybe any other coders willing to lend a hand.
