The extension is initialised by writing 0x55 to 0x(4)a600f0. But there is no need to write 00 to 0x(4)a500fb, since Wii games don't do that. While the Motion Plus is initialising, the value at 0x(4)a600f7 changes from 0x02 to 0x04 to 0x08 to 0x0C to 0x0E then stays at 0x0E. There is no need to read this byte, since games don't. While initialising, the 128 bytes from 0x(4)a60050 - 0x(4)a600cf also change briefly, but randomly, after the extension is initialized. More examples of this data block changing over time can be found here: [https://docs.google.com/Doc?id=dds4pks_606fmcd6zwt&hl=en Three Data Samples from Wii Motion Plus (Google Doc)] (dead link). See this [https://web.archive.org/web/20170828032153/https://docs.google.com/document/d/1hxPAoLksTn0kq1rd5BCJmWKPNkrpub6i62m8cNxlfe8/edit archive].
