Pawa has just released his continuation of the NetHackPSP project originally ported by Virtuamunstaz. The game is now much more playable than the last release, although not fully playable just yet (text input has not been added, it has been planned for the next release). An all new button configuration has been added in this release; Pawa plans to release many more updates to this project soon, great work man, and props for reviving this project!
