Compress game saves to reduce space usage and increase save speed

Original author @bluedoom (until 1.1.11) and @starfi5h (1.1.12), I continue to update to support the latest game version.

Introduction

  • Reduce archive size by 30% / save time by 75% (Compressed by LZ4, on HDD + i7-4790K@4.4G + DDR3 2400MHz)

| Before | After |

| - | - |

| 50MB 0.8s | 30MB 0.2s |

| 220M 3.6s | 147M 0.7s |

| 1010M 19.1s | 690M 3.6s |

Usage

  • You can set compression type for manual saves and auto saves individually.
  • Manual saves are compressed while using the new Save button.
  • You can still get speed benefit while setting compression type to None for auto saves, and for manual saves if using the new Save button.
  • You can decompress saves on load panel.
  • Remember to backup your save(use original save button) before updating game to avoid loading failure.

introduce

  • Reduce archive capacity by 30% / archive time by 75% (LZ4 compression, test environment: mechanical hard drive + i7-4790K@4.4G + DDR3 2400MHz)

| Original archive | After compression |

| - | - |

| 50MB 0.8s | 30MB 0.2s |

| 220M 3.6s | 147M 0.7s |

| 1010M 19.1s | 690M 3.6s |

Instructions for use

  • The compression methods can be set separately for both manual and automatic archiving.
  • Manual archive can be compressed and saved using the newly added save button.
  • Even if it is set to no compression, automatic archiving and manual saving using the new save button can also obtain speed improvements.
  • Archives can be decompressed in the Read Archives panel.
  • If the game has a version update, remember to back up the archive first (use the original save button) to avoid being unable to read the archive after the update.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
