Nine Sols combat inside Hollow Knight’s Godhome

Hollow Sols runs Nine Sols and Hollow Knight together. Nine Sols supplies Yi’s movement, combat and abilities, while Hollow Knight supplies Godhome and its bosses. The author documents 44 playable boss encounters, a fully upgraded Yi and four isolated paired save slots. Version 0.1.0 was published on October 17, 2026. This older release was added to the catalog on October 24.

What you need

Windows x64, legitimate Steam copies of Hollow Knight and Nine Sols, and BepInEx 5.4.23.5 Windows x64 installed separately in both games. Only the exact game and loader hashes in the included BUILD-INFO.json are covered. Review existing mods and loaders for conflicts before installation.

How to get started

  1. Read the creator’s release notes and INSTALLATION.md. Back up saves and review existing mods or loaders for conflicts.
  2. Download HollowSols-v0.1.0-windows-x64.zip and SHA256SUMS.txt from the author release. Verify the archive before extraction.
  3. Install the two mod folders as documented. Run the included read-only Verify-Install.ps1 separately for Hollow Knight and Nine Sols. Stop if any file is missing or mismatched; do not bypass the build checks or save guard.
  4. Start both games through Steam and reach both main menus. Select Hollow Sols Bridge in either game. Use the four mod-owned paired save slots instead of importing vanilla or development saves.
We reviewed the source, release, checksums and setup documents but did not download, install or play the build. The release is experimental and limited to Godhome. Not every jade was tested. Complete Pantheon sequences, every difficulty and binding, challenge persistence, clean-machine reproduction, broader save recovery and more controller, mouse and display combinations remain unverified. Classic and Steel Soul modes are experimental.

Was this made with AI?

The author says all original Hollow Sols code was generated by AI, with no human-written code. Development used Astra 6.0 and Sol 6.1 at Medium or High reasoning effort. The author provided direction, playtesting and feedback.
