The stated functions of software products are not required to work in the games being studied, they only help due to the basic capabilities embedded in them.
The stated functions are only possible, and are not an unconditional statement of their support in all the games being studied.
For a better understanding: games are created on different game engines and their different versions (in particular, there are several hundred versions of Unity) and can often contain additional non-standard modifications, in particular, encryption of code and data, which can be an obstacle to using the functionality of the utilities.
Limitation (for one license): only one instance of the program can be launched at a time! After launching another instance, the previous one will be closed automatically.
Before buying a licensed version, check that the games you need are supported in the demo version (or in the Online version).
