Help/Support Open Roblox in IDA

[DeMoN3X 25 iPhone 7 Plus iOS 14]

Hello,

 

I can't figure out if this game is unity or non-unity.
There is no globalmetadata.dat and when I open the binary in IDA it loads in 15 sec and the useful functions are not present.

Someone can help me ?

thanks in advance !

Hey,

Roblox is likely not Unity. Especially if it doesn’t have the typical Unity structure.

Make sure you are loading the correct executable in IDA.

Roblox is not coded in unity, Its coded in a coding Lang called Luca.

^{I am using the binary file named "Roblox", could this be the wrong one in this case?}

^{The others are .nib .plist .h ...}

Any idea what file it could be? if not the main file you need, then which one? i am confused about this

It's not Unity. The main executable is likely just a caller for other things (I'd a guess a bridge between their Lua code and the Lua engine). Iirc there's a directory with their Lua code and some of it is encrypted. What could be interesting is if you find where that code is decrypted in the small binary you have and try and forge new Lua scripts by decrypting, modifying and then recrypting them using the same key and algo.
