Help! Injecting mod menu, methods of single dex exceed 65536

[Mtankan'Omogolo]

I have been trying to inject a my mod apk into the game's MainActivity smali, when adding "invoke-static {p0}, Lcom/android/support/Main;->Start(Landroid/content/Context;)V" below the OnCreate method, but I get an error saying that methods the number of methods of the dex exceed 65536. The game has many (8) classes.dex files. So I can't add my mod menu.

Welp!
