Nope. GDKE uses DLL injection, which is only for Windows. I don't know if macOS/Linux supports it, but it can't be for mobile (iOS, iPadOS, Android)

How do I find the encryption key for the gde file on Android?

I don't really know. You can't really inject things into an apk. Try using apktool, and watch the files to see if somewhere there is a trace of the key

your best bet would be to use ida/ghidra/etc to reverse the binary and find the encryption key. i have a guide in the description although might be outdated for newer godot games

One new godot (4.x), it isn't anymore this function. I don't know what this is now, but the gdscript::load_byte_code is for godot 3.x

I found open_and_parse, but it's not a function. What should I do next
