@TheStonedModder I tried to open it with the smallest plastic opening tool I had and, since I was afraid that I might break it if I force it a bit more, I decided to give up (for now, at least). I can take a few up-close images later, if you want.
Right now I'm trying to dump one of the games that I own, Ring Fit Adventure and I tried with both MIG Dumper and Migdumptool v0.0.2 and the resulting XCI file had some errors in NxFileViewer v3.0.2.
1) MIG Dumper:
This is the first error I run into:
Failed to open content of NCA section «0»: ResultFsNonRealDataVerificationFailed (2002-4604): Hash error!
The second error(s) I've run into were multiple
NCA entry «...» of type «DeltaFragment» missing. errors.
2) Migdumptool v0.0.2:
Only the multiple
NCA entry «...» of type «DeltaFragment» missing. errors this time around.
I have the latest prod.keys and title.keys.
Both XCI's integrity check resulted with: Original.
I've noticed that some games do not have any errors while some of them have those
NCA entry «...» of type «DeltaFragment» missing. errors. I wonder if that's because the dumps are trimmed or something? How can I avoid getting those errors? By dumping non-trimmed XCIs? If so, is there a guide on how to do that?
EDIT: Just found
this post, so I guess those DeltaFragment are related to the updates and those errors can be ignored and are otherwise normal? Therefore, Migdumptool is a bit more reliable at creating dumps? How to do the same thing with MIG Dumper tool instead?
