What this page covers
People land here after the footer link labeled FAQ. Format hubs and individual game cards can still carry their own three-to-six questions about that URL. Those stay local. This page answers stand-wide questions so the same speech is not pasted onto every card.
For the NSP versus XCI comparison table, open NSP Versus XCI. Longer how-to docs, when published, live under /docs/. This FAQ does not repeat those steps.
How the catalog is arranged
Home is a dump-bench showcase: a short recent table, not the full archive. The paginated list is Switch ROMs. NSP and XCI are first-class hubs in the header. A title card is /switch/{slug}/ — file table first, then Get NSP or Get XCI only when that dump is stored on this host.
Search is Find. It accepts an official name or a Title ID. Filter URLs are not catalog landings. Horror genre, when it exists, is kept out of the public index on purpose.
Stand questions
Is romsns.xyz a store?
No. This host is a Switch ROM catalog: tables of titles, formats, sizes, and checksums. There is no cart, no checkout, and no Nintendo license for sale. A Get NSP or Get XCI button is a first-party file gate on this host when a dump is stored — not a purchase.
What is the difference between NSP and XCI here?
NSP is the digital package format (PFS0). XCI is a cartridge image (HFS0). This catalog lists whichever format is stored for a title. It does not pick a “better” format and does not invent the other file. The comparison table lives on the NSP versus XCI docs page; install walkthroughs are separate docs, not this FAQ.
Why is there no file on a listing?
A game page can exist as metadata only. Get NSP / Get XCI appear when a first-party dump is stored for that URL. Empty verified fields are omitted rather than filled with “unknown.” A missing button means this host does not currently serve that file — not that the title failed a scan, and not that a second format exists off-page.
What is a Title ID?
A Title ID is the 16-character hexadecimal id Nintendo assigns to a piece of Switch software (for example 0100000000010000). Search on this site accepts a title name or a Title ID. On a ticket, the field is optional but it stops duplicate guesses when several dumps share a similar name.
How is the catalog arranged?
Home is a short showcase, not the full archive. The paginated table is /switch-nsp-files/. NSP and XCI have their own format hubs. A game card lives at /switch/{slug}/ and shows the file table before any Get button. Genre hubs sit under the catalog path. Search is /find/ and is not an indexable landing.
Why does a title list only NSP or only XCI?
Rows follow stored dumps, not a wish list. If only NSP is stored, the card does not promise an XCI. If only XCI is stored, it does not promise an NSP. Size labels are the listed dump on that page, not a sum of both formats.
What does lawful backup mean on this site?
Copy on this host talks about files for a lawful backup or research workflow you already have a right to. It is not permission to take a game you do not own, and it is not legal advice. Whether a given file is lawful for you depends on your facts and your jurisdiction — this catalog does not decide that.
Should I open a ticket or report an issue?
Ticket is for a title or format that is not in the catalog yet. Issue is for a broken listing that already exists: wrong Title ID, bad checksum, dead gate, or mismatched region. Search first. One title per ticket. Neither form promises a reply time, and a ticket does not guarantee the title will appear.
What do checksums on a game page mean?
When a file row prints a checksum, it is the value stored for that dump on this host. Compare it to the file you received before you treat the transfer as complete. A mismatch is an issue report, not a ticket. This site does not claim the file is malware-free.
Why are NSZ and XCZ not listed?
Catalog formats on romsns.xyz are NSP and XCI. Compressed twins (NSZ / XCZ) are not rows in this table. Do not assume a listing hides a compressed copy behind the same slug.
I cannot find a title. What should I do?
Use Find with the official name or the Title ID. Check both format hubs if you care about NSP versus XCI. Home only shows a short recent table, so a missing row there is not proof the title is absent. If the catalog still has no card, open one ticket for that title.
Are comments and stars part of the file listing?
No. When a game page shows stars or a comment form, those are visitor marks on the card. They are not a review score from Nintendo, not a virus scan, and not a substitute for the file table. Guest comments wait for moderation and do not change whether a Get button is shown.
