Hi there, I'm encountering a problem where I cannot boot games from my SD card on SYSMMC CFW which I copied over from a backed-up Nintendo folder prior to modding my Switch Lite. There are other posts discussing this code but most are regarding EMUMMC however I can't seem to get my legit Nintendo account linked games to run on this mode. They do run fine on semi-stock and OFW so I am wondering if these games require Nintendo's servers to be able to boot as I'm currently using the Sthetix HATS pack with dns.mitm, exosphere and prodinfo blanking enabled.

Out of curiousity I did disable prodinfo blanking for SYSMMC but then I got a separate 2155-8007 error code, enabled flight mode but the game requests for me to disable it. I updated my firmware using Daybreak from 18.10 to 19.01 but no luck. I also tried using syspatch 1.5.5 but I could not boot into the OS with it as I kept getting "failed to apply nosigchk error" so I reverted back to the HATS files.

The only thing I haven't tried yet is unlinking/relinking my account but I am wondering if it is safe to do on SYSMMC or if all of this normal behaviour to prevent bans on this mode? Appreciate any and all help with this.
