I'm only going on what info has been passed to me. The normal Boot2 menu does not have Wiimote support and I can testify to that. Several people have tried cboot2 and have complained their Wiimote doesn't work.
Loading cboot2 with bootmii-IOS may support Wiimote I really don't know.
Not really doing much Wii stuff these days.
well, on the guide i made ios249 is installed with help of cboot2 and i have not heard any complains about wiimote not working. they do, at least from HBC boot. i dunno what is going on if you load it from bootup...
