MVSC-DHC-v9.1-secret-palettes-r2 — prepared local candidate

This patch-only package contains no game archive, key, emulator or save state.
Supply clean encrypted Marvel vs. Capcom Euro980123 (mvsc.zip), either the 21
member MAME set or the same 20 members without mvsc.key for FBNeo/Fightcade.
Exact member names, sizes and SHA256 values are in MVSC-DHC-v9.1-secret-palettes-r2.patch.json.
Equivalent repacked inputs are accepted. Present foreign keys, changed members,
other revisions and already-patched archives are refused.

Windows: drag your clean mvsc.zip onto the included MVSC-DHC-v9.1-secret-palettes-r2.cmd.
Python3.9 or newer on macOS/Linux/Windows, from this extracted folder:
  python3 mvsc_patch.py "/path/to/mvsc.zip" --spec MVSC-DHC-v9.1-secret-palettes-r2.patch.json --out "/path/to/new-output"

The installer writes mvsc_dhc_v9.1_secret_palettes_r2.zip plus its receipt; it preserves the input
and refuses existing output files. Copy the result into a separate emulator
ROM folder, then rename that copy to mvsc.zip. Keep the clean input as a backup.
Every output member matches candidate 7eff99093cf0804aeb01d7c2ce5ba95f9901e5f55f85bb01075340863a8bdd07; ZIP container hashes
can differ with input order/metadata/compression. A missing key remains missing.
No ROM is downloaded and no network operation is performed.

This default diagnostic build retains original stock throw behavior. No optional
stock-grab compatibility variant is included.

Prepared on 2026-10-02. Local packaging checks passed with Python 3.14.7
and the actual embedded PowerShell 7.6.5 body on macOS. Native Windows CMD,
Windows PowerShell5.1 and Fightcade/rollback acceptance remain unverified.
Packaging preparation does not authorize publication or establish release
acceptance. Gameplay scope and remaining issue status belong to the candidate
qualification; this package is marked prepared, releaseAccepted:false.

This secret-palettes-r2 revision restores the exact original P/K body and
presentation palettes for Gold War Machine, Orange Hulk, Red Venom, Shadow Lady
and Lilith, and replaces their four added single-button body colors. Paired
choices are also checked and replaced where needed for distinctness. All 45
secret body choices are compared with regular REMIX colors and native P/K,
including Ryu forms, and receive visual review. All other fighter colors remain
exact. Native ancillary rows anchor new colors; shared effect code is retained.

Read V91_DISTINCT_SECRET_PALETTE_CREDITS_20261002.md for the indexed source mapping,
Discord references, new contributor credits and native test limits. The included
V91_PALETTE_CREDITS_20261002.md and base-candidate-qualification.json document the
preceding frozen palette candidate; the secret revision notes supersede its
first-six-unchanged claim only for these five secret forms.

The preceding candidate's bounded DHC route/state changes are retained byte for
byte. Their checks and remaining issue status are recorded in V91_ROUTES_20261002.md
and base-candidate-qualification.json. New candidate-qualification.json binds this
revision and distinguishes newly tested palette behavior from inherited checks.
Separate super-effect screenshots remain research references unless a native
indexed row and reader were independently mapped. These notes do not establish
historical sound root causes or broad audible/Windows/rollback correctness.
