The Palm Pre SDK, named Mojo, is not supposed to be available to the general public of developers for a few months. Apparently it was leaked on the internets last night. I was able to get a Hello World program running on the emulator. Here is how I did it.
Java JDK 1.6.0_11 (any 1.6 probably works)
Any modern CPU should work. Mine is 32 bit – not sure about 64 bit.
The emulator takes ~300MB of memory so you’ll probably want at least 1GB.I’ve got 2GB
1 – Download and install VirtualBox
(http://www.virtualbox.org/wiki/Downloads). I am using version 2.2.4
2 – Download and install the SDK.
Palm has the SDK available for free download. I think registration is required.
3 – Start the Emulator.
When the SDK finishes installing you should see a “Palm Emulator” icon on your desktop. Open it.
The emulator should start up and it should look like this:
