*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic memory mapper that spies on Z80 instructions. It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX
*[[Plus2CPC]] and [[Play2CPC]] bring a standard physical Plus cartridge port to the CPC. They are not supported by emulators
*[[M4 Board]] emulates simulates a standard Plus cartridge port on the CPCand handles standard CPR files. It M4 Board is emulated by CPCemu
Why is the Dandanator winning over the Plus2CPC? Because some CPC games (The Sword of Ianna, Los Amores de Brunilda, ...) are released exclusively for it. So emulators are then forced to support it.
