The "Cloning" Nightmare: Parent vs. Clone

If you download a "MAME 0.139 Full Set," you will notice two things: massive file size (roughly 28 GB for ROMs only, excluding CHDs) and duplicated names.

• Parent ROM (e.g., sf2.zip - 40MB): The primary, original version of the game.
• Clone ROM (e.g., sf2ce.zip - 2MB): Champion Edition. In a split set, this file contains only the differences from the parent.
• Non-Merged Set: sf2ce.zip would contain the full 42MB.

Warning for beginners: If you download "MAME 0.139 Romset" and move sf2ce.zip to your device without sf2.zip, the game will not boot. You need the parent.
