A new port and version of Dzzee is out, adding support for the PSP (Homebrew).
The PSP - like the DS in many ways - has a GL1-like interface to its hardware-accelerated rendering features. Other than the NDS, the PSP has beefy hardware and good floating-point performance, so it basically runs at a steady 60 FPS in my tests on a PSP 2000.
