## 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)**


### hekate Global Configuration keys/values (when 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. Max: 20s. |
| noticker=0         | 0: Animated line is drawn during custom bootlogo, signifying time left to skip to menu. 1: Disable. |
| 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. |
| bootprotect=0      | 0: Disable, 1: Protect bootloader folder from being corrupted by disallowing reading or editing in HOS. |
| updater2p=0        | 0: Disable, 1: Force updates (if needed) the reboot2payload binary to be hekate. |
| backlight=100      | Screen backlight level. 0-255.                             |


### Boot entry key/value combinations:

| Config option          | Description                                                |
| ---------------------- | ---------------------------------------------------------- |
| warmboot={FILE path}   | Replaces the warmboot binary                               |
| secmon={FILE path}     | Replaces the security monitor binary                       |
| kernel={FILE path}     | Replaces the kernel binary                                 |
| kip1={FILE path}       | Replaces/Adds kernel initial process. Multiple can be set. |
| kip1={FOLDER path}/*   | Loads every .kip/.kip1 inside a folder. Compatible with single kip1 keys. |
| fss0={FILE path}       | Takes an Atmosphere `package3` binary (formerly fusee-secondary.bin) and `extracts` all needed parts from it. kips, exosphere, warmboot and mesophere if enabled. |
| fss0experimental=1     | Enables loading of experimental content from a FSS0 storage |
| exofatal={FILE path}   | Replaces the exosphere fatal binary for Mariko             |
| ---------------------- | ---------------------------------------------------------- |
| kip1patch=patchname    | Enables a kip1 patch. Specify with multiple lines and/or in one line with `,` as separator. If actual patch is not found, a warning will show up |
| emupath={FOLDER path}  | 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. |
| emummcforce=1          | Forces the use of emuMMC. If emummc.ini is disabled or not found, then it causes an error. |
| emummc_force_disable=1 | Disables emuMMC, if it's enabled.                           |
| stock=1                | Disables unneeded kernel patching and CFW kips when running stock or semi-stock. `If emuMMC is enabled, emummc_force_disable=1` is required. emuMMC is not supported on stock. If additional KIPs are needed other than OFW's, you can define them with `kip1` key. No kip should be used that relies on Atmosphère patching, because it will hang. If `NOGC` is needed, use `kip1patch=nogc`. |
| fullsvcperm=1          | Disables SVC verification (full services permission). Doesn't work with Mesosphere as kernel. |
| debugmode=1            | Enables Debug mode. Obsolete when used with exosphere as secmon. |
| atmosphere=1           | Enables Atmosphère patching. Not needed when `fss0` is used. |
| ---------------------- | ---------------------------------------------------------- |
| payload={FILE path}    | Payload launching. Tools, Android/Linux, CFW bootloaders, etc. Any key above when used with that, doesn't get into account. |
| ---------------------- | ---------------------------------------------------------- |
| id=IDNAME              | Identifies boot entry for forced boot via id. Max 7 chars. |
| logopath={FILE path}   | If it exists, it will load the specified bitmap. Otherwise `bootloader/bootlogo.bmp` will be used if exists |
| icon={FILE 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 defaults 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**: Careful when you define *fss0 core* kips when using `fss0` or the folder (when using `/*`) includes 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). In such cases, the `kip1` line must be under `fss0` line.


### Boot entry key/value combinations for Exosphère:

| Config option          | Description                                                |
| ---------------------- | ---------------------------------------------------------- |
| nouserexceptions=1     | Disables usermode exception handlers when paired with Exosphère. |
| userpmu=1              | Enables user access to PMU when paired with Exosphère.     |
| cal0blank=1            | Overrides Exosphère config `blank_prodinfo_{sys/emu}mmc`. If that key doesn't exist, `exosphere.ini` will be used. |
| cal0writesys=1         | Overrides Exosphère config `allow_writing_to_cal_sysmmc`. If that key doesn't exist, `exosphere.ini` will be used. |
| usb3force=1            | Overrides system settings mitm config `usb30_force_enabled`. If that key doesn't exist, `system_settings.ini` will be used. |


**Note**: `cal0blank`, `cal0writesys`, `usb3force`, as stated override the `exosphere.ini` or `system_settings.ini`. 0: Disable, 1: Enable, Key Missing: Use original value.


**Note2**: `blank_prodinfo_{sys/emu}mmc`, `allow_writing_to_cal_sysmmc` and `usb30_force_enabled` in `exosphere.ini` and `system_settings.ini` respectively, are the only atmosphere config keys that can affect hekate booting configuration externally, **if** the equivalent keys in hekate config are missing.


### 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`. |
| '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        | When menu is forced: bit5: `Run UMS`.                             |
| '0x98' xt_str[128]      | Depends on the set cfg bits.                                      |
| '0x98' ums[1]           | When `Run UMS` is set, it will launch the selected UMS. 0: SD, 1: eMMC BOOT0, 2: eMMC BOOT1, 3: eMMC GPP, 4: emuMMC BOOT0, 5: emuMMC BOOT1, 6: emuMMC GPP,  |
| '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 and only has the `[config]` entry.


### Nyx Configuration keys/values (nyx.ini):

| Config option      | Description                                                |
| ------------------ | ---------------------------------------------------------- |
| themebg=2d2d2d     | Sets Nyx background color in HEX. EXPERIMENTAL.            |
| themecolor=167     | Sets Nyx color of text highlights.                         |
| entries5col=0      | 1: Sets Launch entry columns from 4 to 5 per line. For a total of 10 entries. |
| timeoff=100        | Sets time offset in HEX. Must be in HOS epoch format       |
| homescreen=0       | Sets home screen. 0: Home menu, 1: All configs (merges Launch and More configs), 2: Launch, 3: More Configs. |
| verification=1     | 0: Disable Backup/Restore verification, 1: Sparse (block based, fast and mostly reliable), 2: Full (sha256 based, slow and 100% reliable). |
| ------------------ | ------- The following options can only be edited in nyx.ini ------- |
| umsemmcrw=0        | 1: eMMC/emuMMC UMS will be mounted as writable by default. |
| jcdisable=0        | 1: Disables Joycon driver completely.                      |
| jcforceright=0     | 1: Forces right joycon to be used as main mouse control.   |
| bpmpclock=1        | 0: Auto, 1: Faster, 2: Fast. Use 2 if Nyx hangs or some functions like UMS/Backup Verification fail. |
