Community members on forums like Reddit's r/SwitchPirates often compare these formats:
: You must have all parts (e.g., part1 through part4) in the same folder.
: Right-click only the first part ( part1.rar ) and select "Extract Here." Tools like WinRAR or 7-Zip will automatically pull data from the subsequent parts to create one complete .xci file . XCI vs. NSP Format Review
: There is virtually no difference in in-game performance or frame rates between XCI and NSP formats when using emulators like Yuzu or Ryujinx .
