So, i have a problem, i'm getting the 0x2001, and try to fix it disabling autoGC in hekate options as everything suggests, and it doesn't work, editing BTC.ini, doesn't work also, the gamecard is not being recognised no matter what, so i'm trying to think of anything i could be doing wrong and only 2 options came to my mind:
1. sysMMC is 9.1.0 while emuMMC is 9.0.1 so, gamecards are not showing in emuMMC if sysMMC firmware is higher than in emuMMC? So i should update emuMMC then?
2. I'm missing some patches on my configuration.
Using Kosmos 15.1 and until now i had 0 problems (not used gamecards anyway on emuMMC, since almost everything i play is on sysMMC)
If any other info is needed just tell me and i'll provide. Thanks!

Do gamecards work normally on your emummc? Like can you play load / play them fine?

No, well never used it, since i play normally on sysmmc, and go online with it, and if i tried then maybe i tought is not a big deal. Didn't knew about the nogc until yesterday night, so never tried.

if you use your gamecard on your sysnand 9.1.0 you can't use on emunand 9.0.1, you have burn the efuse of the gamecard and then impossible to use on lower firmware

So i ended updating emummc via choixdujour to 9.1.0 and everything works perfect.
If sysmmc is higher than emummc, you can't use gamecards on emummc.

Thanks!

Is there a way to remove only the installed game card without removing dlc and updates? Just finished a link to the past and wanted to remove the cartridge install only and keep the update if there is one. That way if I want to play later I can just use the cartridge.

With goldleaf yes

So glad for this. Thanks for your work. I have mostly had it work successfully but in some cases not. There was no explicit error either so opening a GitHub issue seemed perhaps too much.

This might be a hard item to test but I have had issue with 2 installs that were kind of ideal choices for me: Momodora: RUTM and Iconoclasts (I have the physical limited carts). Both when installed have produced messages saying that they require software updates to run. Typically installing updates for the cart version has corrected this, but in the case of these, it does not.

I am installing the game carts on AMS 9.1.0 emuMMC and, when necessary, updating them in AMS 9.1.0 Sys and am using your installer version 1.0.1. I believe it may have something to do with version number. My installed version of Momo: RUTM lists its version as 1.0.0 while the cart lists its version as 1.0.3. Similarly Iconoclasts installed lists 1.15h while the cart lists 1.15p (IIRC). I am happy to provide further information. I have on all but one occasion installed the carts to my emuMMC NAND (the one exception, where I tried installing Momo: RUTM to the SD Card was not more successful).

New version of the app is here! Theres a few *important* bug fixes and even more new features.

What's new?

Settings menu.
Game-info menu.
Option to lower keygen (also ticketless install).
Option to choose to install base, update or dlc.
Show the total base, update and dlc per game.
Textures are now entierly cached, slight performance increase whilst installing (~40MiB/s to nand).
Enable / disable music and sound.

What's fixed?

Only the base game was installed previously, this was a huge oversight on my behalf.
Text is now clipped so that it no longer renders off-screen.

Just to explain a bit more about the tickets being installed:

All gamecard's that include a game update will have a ticket (.tik and .cert). This is for the update file.
When launching the gamecard like normal, these tickets are automatically installed.

And now to explain the lower keygen option:

Nca's have 2 types of encryption - titlekey and standard.
titlekey encryption means that it needs the key from the .tik file to decrypt the rest of the nca.
standard crypto has that needed key inside the key area of the nca header (that area is encrypted).
What lower keygen does is it simply re-encrypts the key area with keygen 0. This means that the switch will be able to decrypt it on all fw versions.
If the nca is titlekey, I get the key from the ticket, put it in the key area, then encrypt the key area, finally i set the rights_id field to zero. Simple isn't it!
As for standard nca, I just simply decrypt the key area, then re-encrypt with a lower key.

To be able to use lower keygen, you must have a keys file in either /switch or /switch/gamecard_installer (more info can be found in the readme on the repo page).

Sorry that I didn't see this reply up until now. The good news is that the latest release has fixed this issue

My daughter accidently updated my switch and caused it to crash everytime I booted up cfw but I fixed it by updating hekate, atlas and atmosphere but now all the games I install wont play due to them being "corrupt"

Yes it is discontinued (all my work is), however the installer should still work.

What is the issue that you have?

I'm not too knowledgeable about this but does this wipe the cert when installing?

If say I get banned and I let my friend borrow my original cartridge on his clean switch, could he theoretically also be banned?

Nothing identifiable is installed. If the gamecard has a ticket, that is installed, however that is a common ticket not personal, meaning it doesn’t have anything unique. Also when playing / loading a gamecard like normal, the ticket(s) are installed automatically, so really don’t worry about them.

OldGnashburg · May 6, 2020

Any reason for discontinuation? This app seems pretty much completed but it could break somewhere down the line.

I basically have no interest in making anything for the switch anymore.
