The game seems to have some 'anti CE' measure -- it automatically shuts the game down whenever I try to open the CE and the message "This game is not compatible with Cheat Engine. Please shut Cheat Engine." appears...
Unsigned means the .dll and .exe files aren't digitally signed, this can cause AV software to pick them up as false positive malicious though but it also avoids this thing in some newer games where it detects said signatures and blocks CE from injecting into the game.
Unsure if there's a set of unsigned .dll and .exe files for the recent 6.7.0 release of CE, I know some were posted for 6.6.0 but I haven't checked if there's a update for this newest release although from how I understood there's also utilities for stripping off digital signatures manually which would work as well.
For ver 1.4.1, Is there a way to create table :
1) To activate ALL skill (both and not just 1 of 2)
2) To increace max capacity of items. Like 5 mines from maximum of 99, player can have. (interested max capacity, and not infinity curency).
