What is a ROM set?
Mame allows for different styles of ‘sets’ or ‘where to place ROMS’ At the basic level, a ROM is a chip on a PCB (printed Circuit board) This can be transfered to a file (called a ROM- to maintain consistancy) An arcade game can consist of several ROMs on one PCB. ON the PC side, as a result, a Game can require several ROM files. Due to the size involved, mame needs these files collected together in ZIP files (compressed files using Winzip or similar) But, in mame, there are several games are are similar, but vary slightly. These generally result in the changing on a single ROM chip on the PCB (hence also a change of ROM filename) As a result. Mame is able to work in a child / parent basis.. where is it organised through mame that a ‘child’ set can also obtain needed rom files from the ‘parent’ zip file. As a result of this there exists the possibilty for 3 different types of ‘SETs’ Not Merged Sets – These invole EVERY romfile being stored in EVERY zipfile needed for a given game… Th
