Even if you find a clean file, your iPhone or Android 14 cannot natively run Java (J2ME) games. You would need an emulator like J2ME Loader . While that works, the tactile experience of pressing physical number keys (2 for up, 5 to shoot) is lost on a glass touchscreen.
Search for "Peter Jackson’s King Kong J2ME ROM" and run it via J2ME Loader on Android. If you want to stay safe: Do not type "Waptrick" into your browser. The nostalgia is not worth the malware.
The original Waptrick is dead. Current sites using the "Waptrick" name are honeypots for malware. Downloading a .jar or .jad file from these sites on a modern Android phone is a fast track to ransomware, SMS toll fraud, or adware that you cannot uninstall.
