Well the title says it all really. The pdaXrom site says "pdaXrom has been tested on Sharp Zaurus SL-C700/750/760/860 but is currently being ported to other architectures."
The G4Z page says G4Z is based on pdaXrom.
So will g4z work on an sl5500?
For that matter where do I download g4z? the links on its page seem to point to zaurus.spy.org, which seems to have been down for a while.
