    So I was playing Pokemon Yellow on 10.7 sysNAND. The game won't boot on my 9.2 emuNAND due to not matching keys or something. But for some reason it did boot in Gateway mode using 9.2 emuNAND (NANDs are linked!). But it immediately corrupted my save file. I had totally forgotten about that save file encryption stuff, and I paid for it. And vice versa, an existing save gets corrupted when changing from Gateway 9.2 to 10.7.

    My question is, why exactly did the game boot in 9.2 Gateway mode and not in 9.2 standard emuNAND? And can I force Gateway mode (while staying on 9.2) to use the same save file encryption keys as on 10.7? Thanks.

    I don't think that makes any difference.

    Gateway is within its own world, don't mix it with other things.

    You clearly don't know what you're talking about. But I appreciate your input nonetheless!

    Wait, you have A9lh on 10.7 ?
    And emunand on 9.2?
    If that's so gateway emunand on different portion of your 3ds...i think.

    Oh, I forgot to mention that both NANDs are linked (two NANDs, one game installation).

    Depends on the options you had set in the GW menu. It's very possible you had a pre-7.x encryption save when playing in GW mode.

    Edit, I believe you need to press select to bring up the GW menu then press Up.

    Are you sure? I played the game for the first time on 10.6 ReiNAND with I think was the latest FIRM.

    Is it a 3DS game?
    In any case, where you play it wouldn't matter. The problem is the second you fire up GW with pre 7.x encryption, the game would of immediately been unable to decrypt the save and then threw the corruption screen.

    I don't exactly play Pokemon, and the last time I remember the color games, they were on Gameboy? (so I have no idea if this an e-shop game, gb injection etc..)

    Yes, it's an official VC game purchased for €9,99 from the eShop.

    Anyways I had posted it above, but you can change the save encryption from the GW multi-rom menu by pressing Up.

    As to why it wouldn't boot in emuNAND. If it's a legit game, it's very likely signed with recent firm keys (10.x+) and like you said, 9.2 is too low to run it. (My guess is you got the endless 3DS screen)
    Gateway patches those checks out and also patches out any AP and firmware spoofs which is what allowed it to run in GW mode.

    I didn't know that you can do that. I started the game from scratch and I'm a bit reluctant to try this since there is a chance my save will corrupt again. But then again, I guess I can backup my save and restore it. Thanks man :)

    Newer Official eshop games will not work on old firmwares (pre 9.6) as a new type of encryption was added in 9.6 afaik it shouldnt work in gw mode either unless you use a cryptofixed version yhat has the 9.6 encryption removed
