 Which looks like InitFromFlash(0x1F00,?);
 
+Good news! It doesn't look like InitFromFlash is necessary. It might
+just be a hook for them to patch the init that is grabbed from rom or
+something.
+
+Checking if buffer_radio_init is important. If so, then I need to
+figure out how it's used and, preferably, what it means.
+
+So buffer_radio_init is necessary for their code to work. I'm not sure
+if it is necessary for the radio of if it's necessary for there app.
