It sounds like the RC5 application is not running the same core that the

I had written one, but the lack of documentation for testing the core prompted
me to drop the project. I was trying to use the "new" function prototype but it
didn't fit in seamlessly with the test harness. If someone would make this
easy, I would be willing to complete my work on it.
