CTCaer 4160037c81 emummc: Add boot entry emuMMC selection
Using the key `emupath` on a boot entry will load the selected emuMMC.
This can also be forced by using the correct boot cfg storage bit and writing the path at the emummc path offset. Check readme for these.

This can only be used if the emuMMC was created via Nyx. because of the raw_based and file_based files that have emuMMC info.
(emupath=emuMMC/RAW1, emupath=emuMMC/SD00, etc)

Custom Nintendo Switch bootloader, firmware patcher, and more.
## Bootloader folders and files
| Folder/File | Description |
| ------------------------ | --------------------------------------------------------------------- |
| bootloader | Main folder. |
| \|__ bootlogo.bmp | It is used when custom is on and no logopath found. Can be skipped. |
| \|__ hekate_ipl.ini | Main bootloader configuration and boot entries. |
| \|__ patches.ini | Add external patches. Can be skipped. A template can be found [here](./res/patches_template.ini) |
| \|__ update.bin | If newer, it is loaded at boot. For modchips. Auto updated. Can be skipped. |
| bootloader/ini/ | For individual inis. 'More configs...' menu. Autoboot is supported. |
| bootloader/res/ | Nyx user resources. Icons and more. |
| \|__ background.bmp | Nyx - custom background. |
| \|__ icon_switch.bmp | Nyx - Default icon for CFWs. |
| \|__ icon_payload.bmp | Nyx - Default icon for Payloads. |
| \|__ icon_lakka.bmp | Nyx - Default icon for Lakka. |
| bootloader/sys/ | For system modules. |
| \|__ emummc.kipm | emuMMC KIP1 module. Important! |
| \|__ libsys_lp0.bso | LP0 (sleep mode) module. Important! |
| \|__ libsys_minerva.bso | Minerva Training Cell. Used for DRAM Frequency training. Important! |
| \|__ nyx.bin | Nyx - Our GUI. Important! |
| \|__ res.pak | Nyx resources package. Important! |
| bootloader/screenshots/ | Folder where Nyx screenshots are saved |
| bootloader/payloads/ | For payloads. 'Payloads...' menu. Autoboot only supported by including them into an ini. All CFW bootloaders, tools, Linux payloads are supported. |
| bootloader/libtools/ | Future reserved |
| sept | Sept folder. This must be always get updated via the Atmosphère release zip. Needed for tools and booting HOS on 7.0.0 and up. Unused for booting HOS if `fss0=` key is defined. |
**Note**: Sept files for booting 7.0.0 and up are expected at /sept folder at root of sd card.
## Bootloader configuration
The bootloader can be configured via 'bootloader/hekate_ipl.ini' (if it is present on the SD card). Each ini section represents a boot entry, except for the special section 'config' that controls the global configuration.
There are four possible type of entries. "**[ ]**": Boot entry, "**{ }**": Caption, "**#**": Comment, "*newline*": .ini cosmetic newline.
You can find a template [Here](./res/hekate_ipl_template.ini)
### Global Configuration keys/values when boot entry is **config**:
| Config option | Description |
| ------------------ | ---------------------------------------------------------- |
| autoboot=0 | 0: Disable, #: Boot entry number to auto boot. |
| autoboot_list=0 | 0: Read `autoboot` boot entry from hekate_ipl.ini, 1: Read from ini folder (ini files are ASCII ordered). |
| bootwait=3 | 0: Disable (It also disables bootlogo. Having **VOL-** pressed since injection goes to menu.), #: Time to wait for **VOL-** to enter menu. |
| verification=2 | 0: Disable Backup/Restore verification, 1: Sparse (block based, fast and not 100% reliable), 2: Full (sha256 based, slow and 100% reliable). |
| autohosoff=1 | 0: Disable, 1: If woke up from HOS via an RTC alarm, shows logo, then powers off completely, 2: No logo, immediately powers off.|
| autonogc=1 | 0: Disable, 1: Automatically applies nogc patch if unburnt fuses found and a >= 4.0.0 HOS is booted. |
| updater2p=0 | 0: Disable, 1: Force updates (if needed) the reboot2payload binary to be hekate. |
| backlight=100 | Screen backlight level. 0-255. |
### Possible boot entry key/value combinations:
| Config option | Description |
| ---------------------- | ---------------------------------------------------------- |
| warmboot={SD path} | Replaces the warmboot binary |
| secmon={SD path} | Replaces the security monitor binary |
| kernel={SD path} | Replaces the kernel binary |
| kip1={SD path} | Replaces/Adds kernel initial process. Multiple can be set. |
| kip1={SD folder}/* | Loads every .kip/.kip1 inside a folder. Compatible with single kip1 keys. |
| fss0={SD path} | Takes a fusee-secondary binary and `extracts` all needed parts from it. kips, exosphere, warmboot and sept. |
| fss0experimental=1 | Enables loading of experimental content from a FSS0 storage |
| kip1patch=patchname | Enables a kip1 patch. Specify with multiple lines and/or as CSV. If not found, an error will show up |
| fullsvcperm=1 | Disables SVC verification (full services permission) |
| debugmode=1 | Enables Debug mode. Obsolete when used with exosphere as secmon. |
| atmosphere=1 | Enables Atmosphère patching. |
| emupath={SD folder} | Forces emuMMC to use the selected one. (=emuMMC/RAW1, =emuMMC/SD00, etc). emuMMC must be created by hekate because it uses the raw_based/file_based files. |
| nouserexceptions=1 | Disables usermode exception handlers when paired with Exosphère. |
| userpmu=1 | Allows user access to PMU when paired with Exosphère. |
| emummc_force_disable=1 | Disabled emuMMC if it's enabled. |
| stock=1 | Disables unneeded kernel patching when running stock or semi-stock. `If emuMMC is enabled, emummc_force_disabled=1` is required to run completely stock. |
| id=idname | Identifies boot entry for forced boot via id. Max 7 chars. |
| payload={SD path} | Payload launching. Tools, Linux, CFW bootloaders, etc. |
| logopath={SD path} | If no logopath, `bootloader/bootlogo.bmp` will be used if exists. If logopath exists, it will load the specified bitmap. |
| icon={SD path} | Force Nyx to use the icon defined here. If this is not found, it will check for a bmp named as the boot entry ([Test 2] -> `bootloader/res/Test 2.bmp`). Otherwise default will be used. |
**Note1**: When using the wildcard (`/*`) with `kip1` you can still use the normal `kip1` after that to load extra single kips.
**Note2**: When using FSS0 it parses exosphere, warmboot and all core kips. You can override the first 2 by using `secmon`/`warmboot` after defining `fss0`.
You can define `kip1` to load an extra kip or many via the wildcard (`/*`) usage.
**Warning**: Never define *fss0 core* kips when using `fss0` and make sure that the folder (when using `/*`), does not include them.
This is in case the kips are incompatible between them. If compatible, you can override `fss0` kips with no issues (useful for testing with intermediate kip changes).
### Payload storage:
hekate has a boot storage in the binary that helps it configure it outside of BPMP enviroment:
| Offset / Name | Description |
| ----------------------- | ----------------------------------------------------------------- |
| '0x94' boot_cfg | bit0: `Force AutoBoot`, bit1: `Show launch log`, bit2: Boot from ID, bit3: `Boot to emuMMC`, bit7: `sept run`. |
| '0x95' autoboot | If `Force AutoBoot`: 0: Force go to menu, else boot that entry. |
| '0x96' autoboot_list | If `Force AutoBoot` and `autoboot` then it boots from ini folder. |
| '0x97' extra_cfg | bit7: Force Nyx to run `Dump pkg1/2`. |
| '0x98' xt_str[128] | Depends on the set cfg bits. |
| '0x98' id[8] | When `Boot from ID` is set, it will search all inis automatically and find the boot entry with that id and boot it. Must be NULL terminated. |
| '0xA0' emummc_path[120] | When `Boot to emuMMC` is set, it will override the current emuMMC (boot entry or emummc.ini). Must be NULL terminated. |
If the main .ini is not found, it is created on the first hekate boot.
