How can I do this? I've heard you can, just have no clue what to do.

Screen shot :
(disk-based games only) press B and 2 in game on first wiimote and it will create a RAW capture of the frame buffer on root of usb in Uneek+DI Rev140

YCbYCr2BMP.rar : from crediar
-CMD Prompt app that converts RAW pics to BMP format, if you want to use a PC to view snapshots instead of the built in Wii Sneek Menu RAW snapshot viewer
-YCbYCr2bmp.exe raw.bin fancy.bmp
