Hacking Can't play some installed .NSPs on 9.0.0 (Kosmos)

[KiraGio]

Uhm, sorry for the newbie question.
I have installed Kosmos for 9.0.0 and everything is working.
The problem is that whenever I try installing a .nsp file and gets installed, the game prompts with a "Game requires an update".

I've tried with Dragon Quest Builders and everything seems to work (It asks me for an update BUT I can also play it without) but, trying with Mario Kart 8 and SSBU seems to not work, prmpting me with a "Game needs to be updated" or even "Game hasn't been downloaded, press to download"

I tried updating SSBU but the update 5.0 (that worked on 8.0.1) now updates the game up to 1.2.1 and still prompts me with the must-do update.

I installed the sig patches that Kosmos gave with the new version.

Any help?

EDIT: Oh, yea, forgot to say. SSBU I actually own has a gamecard while Mario Kart and DQ Builders2 I do not.

P.s. I use Tinfoil, Nut to install and tried "Convert to default crypto" and didn't work.

Seems to me your signature patches are missing, your game update NSPs are corrupted, or the NSP installers aren't fully compatible with 9.0 just yet.
Have you tried to install any other games? No luck?
