KytyPlus v4.1 Release Notes

KytyPlus v4.1 is a feature release focused on game-image format support. The main addition is native exFAT game image loading, together with the OodleSharp decompressor dependency used by the package helper and tests.

What’s new

• exFAT game image loading

  • Launcher can now load standalone .exfat game images in addition to .ffpfsc.
  • New Load Game option: exFAT game image (.exfat)...
  • Image-open path, library scanning, and delete-game handling now recognize .exfat images.
  • Emulator CLI --game path also accepts .exfat game images.

• Shared image-path helper

  • Added IsGameImagePath so image checks are handled consistently across the launcher and emulator.
  • Image checks now cover .ffpfsc and .exfat from one place.

• Dependency added

  • Added 3rdparty/OodleSharp as the NAPS/Oodle decompression dependency used by the package helper and regression tests.
