PicoDrive was actually written by a guy calling himself 'notaz' using cpu emulations by fDave and Reesy. Please consider making a small donation to him. http://notaz.gp2x.de/ Also note he has programmed the SVP 3D chip emulation. http://notaz.gp2x.de/svp.php

PicoDrive for Maemo sound is working quite nicely. But it has small skips/dropouts audible in almost all games. I was not able to eliminate them by disabling the scaler and increasing frameskip very high. Do you have information where this is occurring in the pipeline?

Savegames are not working for me; it is pretty important to support multiple savestates for RPGs. Optimal would be some mappable keys for quickly saving and loading 4-9 states.
