DPM Vs RPMS

[arisma]

What is better option for use with DT?
i have to create my backups with dpm or rpms for better use of dt or depends of the game protection?

For some copy protections it's necessary to read the DPM. This is called Data Position Measurement. So when you read the DPM you read the physical position of the data and other physical propertities of the CD. It's impossible to write these data on a cd-r like it is written on the original cd. At this point you need the RMPS emulation, it emulates the position of the data and the other properities stored in the DPM. When you write the RMPS data on a cd ,which you got by reading the dpm, then it's necessary to emulate these data with the RMPS emualtion of DT.
