gx2 same as all other games....just works...dont know about loadiine v4 or loadiine v3, but as i say gx2 works fine
You can't run it ? what are the error ?freeze ?
Is it your backup of Splatoon ok ?
IIRC doesn't v1 work with it?
For Splatoon you need the following release: "loadiine_gx2_beta_build_20160214"
Didn't worked for me with the most recent release, but worked with that build after losing some hours searching for a way to play it
By the way, the EUR released worked on my US console
