Q: Can I extract assets from mobile games (APK/IPA)?

Q: Is there a Mac or Linux version?
A: There is no native version, but UnityEx Ultimate runs well on Wine or Proton (Linux) and CrossOver (Mac). Alternatively, use AssetStudio for native cross-platform extraction.

Q: Can I use UnityEx Ultimate to extract my own unfinished Unity project?
