I just bought a brand new NEO SD PRO from Terraonion website but sadly I have same issue, so i decided to follow this tutorial but it's only work when i totally remove the two spacer
So it's not solved for me.
i'm very happy by chosing the neo sd pro but the only thing is i didn't bought it with black friday offer so it's very very hurts my heart by spending 130 € custom fees and get this issue.
I feel very scary for my console everytime i put the cartbridge inside.
Fingers crossed for a solution.
Thanks very much for reading me and hope evreyone is safe at this moment.
