Full non-merged ROMsets are a type of ROMset that contains all the data from the original arcade game, without any merging or splitting of files. This means that each ROMset contains all the necessary files to run a specific game, without any dependencies on other ROMsets. Full non-merged ROMsets are considered the most comprehensive and accurate way to emulate arcade games, as they preserve the original data and structure of the game. mame 2003-plus reference: full non-merged romsets
