Atmosphère 0.9.0 released, introduces emuMMC support
Today's the big day! Atmosphère, the Nintendo Switch CFW made by @SciresM and his team, has reached a new milestone, thus marking the release of version 0.9.0!
A few improvements were made to creport and dmnt's cheat virtual machine, adding more detailed output and 32-bit game support for the former and a new debug opcode for the latter, however, most users will be excited to know that a highly anticipated feature has finally been included: we're talking about emuMMC, of course! This has been possible thanks to a collaboration between @SciresM, @_hexkyz_, @m4xw and @CTCaer and it's the first publicly available free and open source implementation of NAND redirection for the Switch. Atmosphère's emuMMC can be enabled by editing the file emummc\emummc.ini and setting "emummc_enabled" under its relative section to 1. The feature is able to redirect reads and writes to either a separate partition on the card (recommended) or loose files in a directory with the archive bit set: in order to choose one of the two, you have to set either "emummc_sector" or "emummc_path" to a valid value (read the changelog for more information). By default, emuMMC will use a different Nintendo folder called "Nintendo_<emummc_id>", however, you can choose whichever directory you like by setting "emummc_nintendo_path" to your desired one.
While the current implementation is in a working state, the developers stress it should still be considered an experimental feature; as such, users who want to set emuMMC as their main boot option are advised to wait until any eventual bugs are fixed in the next update. Some planned features are also currently not included, for example having a separate atmosphere folder for each emuMMC.
The official changelog is as follows:
Changelog said:0.9.0 is Atmosphère's eighteenth official release.
fusee-primary was last updated in: 0.9.0.
With thanks to the @switchbrew team, Atmosphère 0.9.0 is bundled with hbl 2.1, and hbmenu 3.0.1.
The following was changed since the last release:
For information on the featureset supported by 0.9.0, please see the official release notes.
- Creport output was improved significantly.
- Thread names are now dumped on crash in addition to 0x100 of TLS from each thread.
- This significantly aids debugging efforts for crashes.
- Support was added for 32-bit stackframes, so reports can now be generated for 32-bit games.
- dmnt's Cheat VM was extended to add a new debug opcode.
- With thanks to/collaboration with @m4xw and @CTCaer, support was added for redirecting NAND to the SD card (emummc).
- Please note, this support is very much beta/experimental.
- It is quite likely we have not identified all bugs -- those will be fixed as they are reported over the next few days/weeks.
- In addition, some niceties (e.g. having a separate Atmosphere folder per emummc instance) still need some thought put in before they can be implemented in a way that makes everyone happy.
- If you are not an advanced user, you may wish to think about waiting for the inevitable 0.9.1 bugfix update before using emummc as your default boot option.
- You may especially wish to consider waiting if you are using Atmosphere on a unit with the RCM bug patched.
- Emummc is managed by editing the emummc section of "emummc/emummc.ini".
- To enable emummc, set emummc!emummc_enabled = 1.
- Support is included for redirecting NAND to a partition on the SD card.
- This can be done by setting emummc!emummc_sector to the start sector of your partition (e.g., emummc_sector = 0x1A010000).
- Support is also included for redirecting NAND to a collection of loose files on the SD card.
- This can be done by setting emummc!emummc_path to the folder (with archive bit set) containing the NAND boot partitions' files "boot0" and "boot1", and the raw NAND image files "00", "01", "02", etc. (single "00" file with the whole NAND image requires exFAT mode while multipart NAND can be used in both exFAT and FAT32 modes).
- The Nintendo contents directory can be redirected arbitrarily.
- By default, it will be redirected to emummc/Nintendo_XXXX, where XXXX is the hexadecimal representation of the emummc's ID.
- The current emummc ID may be selected by changing emummc!emummc_id in emummc.ini.
- This can be set to any arbitrary directory by setting emummc!emummc_nintendo_path.
- To create a backup usable for emummc, users may use tools provided by the hekate project.
- If, when using emummc, you encounter a bug, please be sure to report it -- that's the only way we can fix it.
- General system stability improvements to enhance the user's experience.
A reminder for people new to Switch hacking: emuNAND/emuMMC will not help if your console is banned, has been flagged by Nintendo or if your NAND has been "tainted" by running CFW/homebrew and you don't have a clean backup. All currently available implementations are preventive measures which let you have a clean system partition that you can use with your legit games online (no homebrew or game backups) and another separate one (the emuNAND/emuMMC itself) on which you can run everything else offline without fearing a ban. The latter is created from a copy of your Switch's internal memory: as such it will not let you evade a ban, nor clear any modifications or error logs made by homebrew apps.
