手順とヒント（Unreal / GVAS）

使い方

  1. Back up the entire save folder. Close the game before copying or uploading files.
  2. Upload your .sav or binary save. Read the automatic notice above the hex grid: it tells you if the file starts with GVAS, is gzip-wrapped, etc.
  3. Click an offset in the hex grid to inspect int32 / float32 / float64 (little-endian) in the sidebar. Edit a single byte with the hex field + Apply, or plan larger edits carefully.
  4. Download only when you understand what you changed — UE strings are length-prefixed; this tool does not recompute those lengths for you.
  5. Restore from backup immediately if the game rejects the save.

制限事項

  • This page does not parse the full GVAS object tree — you are editing raw bytes. Wrong edits break checksums and string length fields.
  • If the file is gzip-compressed, the grid shows compressed bytes unless you use an external tool to decompress first.
  • Steam Cloud or launcher sync can overwrite your file — disable cloud for that title while testing.
  • For games that store JSON inside Base64, use the Base64 or JSON tools instead.
