Yes, they are or at least supposed to be. Which platform you're on ?
I'll double check. It's possible that your version is an earlier

Did you try ibrowse demo ? I am (almost) certain that I ran that
before releasing the test version. If ibrowse fails in your platform,

a bit of a hassle maybe, but 8bit in my world just does not
have enough resolution to be useful.
