Play Pop'n Music Portable 2 with a Pop'n controller (remotejoy-minus)
I’ve set things up so that the Pop'n Controller (RU014) for PS1/PS2 can be used with the PSP.
This makes it possible to play *Pop'n Music Portable*.
Using this requires "remotejoy-minus"; since it is open-source, you can also build it yourself by referring to the URL below.

I believe the Pop'n Controller 2 and arcade-style controllers for PS1/PS2 are also compatible, but I don't own them, so I can't test them out.
The downside is that the buttons make a loud noise when pressed...
