You can drag-and-drop sf2.zip (Street Fighter II) onto your SD card, and it works. You do not need sf2.zip , sf2a.zip , sf2b.zip , and sf2parent.zip all sitting in the same folder.

ROMsets contain copyrighted material. Only download if you own the original arcade PCBs or are in a jurisdiction allowing backup/educational use. No direct download links are provided; instead, reference sources are given.
