Hekatos 6.5.5 updates its bootloader base
Hekatos 6.5.5 updates the unofficial hekate fork to hekate 6.5.5 and Nyx 1.9.5. The release adds support for HOS 23.5.0, the Nintendo Switch operating system version named in the release notes.
Hekatos combines a graphical bootloader with tools for launching custom firmware, official firmware, Android, Linux, and external payloads. Its Nyx interface supports touchscreen and Joy-Con input, configurable themes, boot-entry management, emuMMC tools, storage utilities, hardware information, and backup and restore functions.
FAT32 nogc offsets corrected
Version 6.5.5 fixes the FAT32 nogc offsets. Hekatos documents nogc as a boot configuration patch that can be applied automatically when the relevant conditions are met. The corrected offsets update the locations used by that patch on FAT32 setups.
The release also retains Hekatos’s wider storage features, including emuMMC creation and management, SD-card partition tools, and USB mass-storage access for SD, eMMC, and emuMMC storage.
emuMMC and Mariko sleep firmware updated
The update refreshes emuMMC firmware and sleep firmware for Mariko hardware. These are low-level components used by the boot environment and its emulated MMC and sleep-related functions.
4GB and 8GB packages retain ofw=1 support
Hekatos 6.5.5 is available in separate 4GB and 8GB packages: Hekatos-6.5.5-4GB.zip and Hekatos-6.5.5-8GB.zip. The release also preserves ofw=1 support for boot entries that launch official firmware through the bootloader.
Hekatos supports configurable entries for custom firmware, official firmware, stock system configurations, Android, Linux, and payloads. Entries and global options can be managed through Nyx or the bootloader configuration file, including autoboot and emuMMC settings.
What Hekatos provides
Hekatos is an unofficial fork of hekate. Its project documentation states that it is not the official hekate project and is not affiliated with or endorsed by CTCaer. The fork adds launch options and provides separate 4GB and 8GB release packaging.
