I don't have a Lego Mindstorm set to play with, but I wanted to try out the emulartor stuff that comes with lejos, the Java VM for the Lego Mindstorms RCX brick.
I downloaded the latest stuff from lejos.org and built it with make. Unfortunately, I didn't get much farther. I tried to run the hworld example in the emulator, but I get a segmentation fault with it. I ran "lejos -o" on the class files, and got a bin (didn't use emu-lejos, since PowerPC is big endian) and then tried to run it through "emu-lejosrun". It crashes right away. Has anyone else tried this? Any luck?
