Magisk, a popular Android root management tool, is experiencing a specific compatibility issue with Android 12 (x86_64) when used on the MEmu emulator. This issue manifests as a failure to patch the boot image (`boot.img`) due to an incorrect detection of the Ramdisk state by Magisk v27.1 and above (including v28.1). While Magisk v27.0 functions correctly on this setup, later versions consistently mark the Ramdisk as `No`, leading to an installation failure and the inability to create the patched `magisk_patched.img` file.

This issue appears exclusive to the Android 12 (x86_64) environment on the MEmu emulator. Notably, patching works seamlessly on MEmu with Android 9 (x86_64) using the same Magisk v28.1 build. The specific boot.img file that fails on Android 12 patches successfully on Android 9, further reinforcing the incompatibility lies within Magisk's detection logic on Android 12 x86_64.

Further investigation reveals a pattern in the error logs: Magisk incorrectly identifies the Ramdisk as `No`, triggering an exception during the file write operation when attempting to create `magisk_patched.img`. This suggests a potential problem with how Magisk accesses or interprets files in the Android 12 x86_64 environment on MEmu.
