MPS
The protection system used is the ModProtectionSystem, abbreviated as MPS. This system is responsible for protecting certain files of DynamX, including models (but not limited to models; it can be textures or other files).
The operation will not be detailed here, but note that the files are encrypted and divided into different parts, making it almost impossible to reconstruct them.
Danger
A pack protection software will be released soon.
