Okay, so I understand what bootmii does, (allows you to backup/restor NAND and load .dol's before the Wii boots) but what I'd like to know is the differences between: boot1, boot2, boot2v3, boot2v4, cboot2 and any others I have left out. Is there a way you can check what you've got? I know that N did something in their 4.2 update stop bootmii, which they have stopped now, but I updated via N the day it came out so I don't know what has happened. Bootmii still works but I was just wondering that would a 3.4/4.0 backup still work on my Wii? I had to use 1.0.5 hackmii so I think I've got boot2v4 or cboot2. Thanks in advance for any help or explanation.
