first bad idea.
use wii Backup Manager instead.
WBFS Manager will corrupt your drive when you delete a game.

Second bad idea.
If you need help, ask us, but please, do not follow random youtube videos. (that's great wanting to help but it's often done by users not understanding what they are explaining, giving outdated links because the video is old and can't be updated, done for a specific plateform and not necessarily the one the user want without knowing he shouldn't follow it)
but whenever I try to load a game, it crashes back to the home screen
You didn't install a custom IOS.
you need to follow a softmod guide to install d2x cIOS in slot 249. (and some guide will also tell you to install in slot 250)
You only need one patched system :
d2x v10 BETA52 for vWii (DO NOT INSTALL BETA53 ! EVEN IF A RANDOM GUIDE TELL YOU TO DO IT)
Slot 249
base 57
version 21010
that's all.
Just extract the link to your SD card, run the installer from the homebrew channel and install what I told just above : d2x v10 r52 base 57 in slot 249.
all your games will work. you don't need any more changes.
note: you said vWii, but posted in the Wii section of the forum.
I linked to the vWii installer, I hope that's the correct one.
if you are on a Wii, let me know and I'll give you the correct version.
