description	Rewraps PS Vita NoNpDrm dump ZIP files so RomM + Argosy Launcher + Vita3K ZX can install them — ensures the Title-ID folder sits at the ZIP root and the filename carries the Title ID in brackets. Use when preparing PS Vita ROM zips for a self-hosted RomM library.

Vita3K ZIP Prep

Take one or more PS Vita NoNpDrm dump ZIPs and rewrap each so it's ready to drop into the psvita RomM library. Full background: /Users/andrew/Vault/Personal/Games/Roms/Vita3K ZX Rom Setup Runbook.md.

Input

One or more ZIP file paths passed as arguments. Paths may be relative or absolute; expand ~ and resolve.

What "ready" means

A ZIP is ready when:

1. The Title-ID folder (PCSA…, PCSB…, PCSE…, PCSF…, PCSG…, PCSH… + 5 digits) sits at the ZIP root — not nested under app/ or any other outer folder.
2. <TITLE_ID>/sce_sys/package/work.bin is present inside the archive (the NoNpDrm license).
3. The filename matches [<TITLE_ID>] <Game Name>.zip.

If a file already meets all three, mark it done and move on. Do not repack unnecessarily.

Processing

For each input ZIP:

1. Inspect

Use unzip -l "<path>" to list contents. Do NOT extract the full archive — these files are large (1–4 GB typical). Detect:

• Title ID: find the first path segment matching ^PCS[A-Z][0-9]{5}(/|$) at any depth. If multiple, prompt the user to disambiguate.
• Nesting depth: how many path components precede the Title-ID folder. 0 means it's at root (good). 1 (e.g. app/PCSE00899/…) or more means needs repack.
• License present: confirm a <TITLE_ID>/sce_sys/package/work.bin entry exists. If not, warn loudly — the dump is unusable, don't repack, ask the user how to proceed.

2. Determine the game name

Priority order:

1. If the source filename already has [<TITLE_ID>] <Name>.zip shape, reuse the <Name>.
2. If the source filename is like <Name> (USA).zip or <Name>.zip, strip region tags and use that.
3. If neither yields a clean name, ask the user for the canonical game name (No-Intro style, e.g. Odin Sphere Leifthrasir).

Do NOT try to parse param.sfo — it's inside the encrypted PFS on some titles and unreliable to read from a zip listing.

3. Repack if nested (skip if already at root)

The zip CLI stores paths as given. To move the Title-ID folder to root, extract only that subtree, then re-zip from its parent:

# Example: input has app/PCSE00899/... nested
work_dir=$(mktemp -d)
unzip -q "<input.zip>" "app/PCSE00899/*" -d "$work_dir"
cd "$work_dir/app"
zip -qr "<output-path>" PCSE00899 -x "*.DS_Store"
rm -rf "$work_dir"

Adjust the unzip glob and the cd target to whatever the actual nesting is (could be app/, dump/, or bare Title-ID with just wrong filename).

If the Title-ID folder is already at root, don't touch the zip contents — just cp or mv to the new filename.

4. Name the output

[<TITLE_ID>] <Game Name>.zip

Write it into the same directory as the source unless the user specified otherwise. Do not overwrite the source zip unless the user confirmed; default is to write alongside with the new name and leave the original.

5. Verify

After each repack, run unzip -l "<output>" | head -5 and confirm the first content entry starts with the Title-ID folder. Also grep for work.bin. Report both to the user as evidence the file is good.

6. Optional move to library

If the user has confirmed they want files moved to their psvita library, the standard destination is /Volumes/Games/library/roms/psvita/. Prompt for confirmation before moving. If declined, leave the file where it was written.

Output to the user

For each input, print a compact status line:

✓ Rick Deckard's Odin.zip → [PCSE00899] Odin Sphere Leifthrasir.zip
  root: PCSE00899/  |  license: found  |  size: 1.9G

or a warning block if something needs the user's attention (missing license, ambiguous Title ID, unclear game name).

Edge cases

• Multiple Title-ID folders in one zip (e.g. base game + update bundled): stop and ask which to package, or offer to produce multiple output files.
• No Title-ID folder found: the archive isn't a Vita dump. Report and skip.
• Zip is actually a .7z or other format: report and skip; this skill is .zip only.
• Existing output filename already exists: append a suffix or ask the user.
• Source path has spaces: quote everything.
