Mine had only 5 screws for this step

I found this helpful teardown vid which shows all the screws you have to remove: https://www.youtube.com/watch?v=80DvlAE8...

Definitely this. The Y1. Those tri wing screws under the stickers on the bottom of the front bezel are in rather tight and anything too small might damage the head.

There are no screws under the two rear rubber pads on the serial number side of my RVL-001(AUS) Wii. I don't know why the author photographed themselves removing those rubber feet. Only remove the rubber pad near the front on that side (as well as the battery compartment, and the screws mentioned in step 4) to get the front bezel off.

I noticed the 1.8mm screw had a slightly larger diameter than the 1.6mm screw. This may help if you (or I) get it mixed up during reassembly.
