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
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. |
| 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. |
Nyx Global Configuration keys/values for (nyx.ini):
| Config option | Description |
|---|---|
| themecolor=167 | Sets Nyx color of text highlights. |
| 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). |
| umsemmcrw=0 | 1: eMMC/emuMMC UMS will be mounted as writable by default. |
| jcdisable=0 | 1: Disables Joycon driver completely. |
| newpowersave=1 | 0: Timer based, 1: DRAM frequency based (Better). Use 0 if Nyx hangs. |
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 |
| exofatal={SD path} | Replaces the exosphere fatal binary for Mariko |
| 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. |
| 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_disabled=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. |
| 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. |
Boot entry key/value Exosphère combinations:
| 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. |
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 | When menu is forced: bit5: Run UMS, bit7: Run Dump pkg1/2. |
| '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.
