Add a configuration option "Full w/ hashfile" to the "verification" option menu, to enable hashfile generation when doing full verification of a backup. When enabled, during full backup verification we save the chunk's SHA256 digest in a hashfile next to the output file we're currently verifying. The performance impact is negligible between "Full verify" and "Full verify w/ hashfile", because we already compute the SHA256 of the chunks when verifying. We save the SHA256 per chunks (4 MB) because due to SE limitations, we can't compute the SHA256 of the whole partition (or rawnand). On the other hand a pure software implementation is way too slow to be bearable, even asm-optimized: between 15 and 90 seconds per 4 MB chunk for crc32/sha1/sha256, depending on the optimizations and the actual algorithm. The output hash file format is as follows: # chunksize: <CHUNKSIZE_IN_BYTES> sha256_of_chunk_1 sha256_of_chunk_2 ... sha256_of_chunk_N |

hekate - CTCaer mod
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. |
|__ update.bin | If newer, it is loaded at boot. For modchips. Can be skipped. |
bootloader/ini/ | For individual inis. 'More configs...' menu. Autoboot is supported. |
bootloader/sys/ | For system modules. |
|__ libsys_lp0.bso | LP0 (sleep mode) module. Important! |
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 |
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.
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. |
backlight=100 | Screen backlight level. 0-255. |
Possible boot entry key/value combinations:
Config option | Description |
---|---|
logopath={SD path} | If global customlogo is 1 and logopath empty, bootlogo.bmp will be used. If logopath exists, it will load the specified bitmap. |
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. |
kip1patch=patchname | Enables a kip1 patch. Specify with multiple lines and/or as CSV. Current available patches nosigchk. |
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 |
stock=1 | Disables unneeded kernel patching when running stock or semi-stock. |
payload={SD path} | Payload launching. Tools, Linux, CFW bootloaders, etc. |
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 core kips when using fss0
and make sure that the folder (when using /*
), does not include them.
Payload storage:
Hekate now has a new 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: 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 | Reserved. |
'0x98' rsvd[128] | Reserved. |
You can find a template Here
If the main .ini is not found, it is created on the first hekate boot.
