DHC V10 — released October 8, 2026

This patch-only package contains no game archive, key, emulator or save state.
Supply your own clean encrypted Marvel vs. Capcom Euro 980123 (mvsc.zip): the
21-member MAME set, or the same 20 members without mvsc.key for FBNeo/Fightcade.
Exact names, sizes and SHA256 values are in MVSC-DHC-v10.patch.json.
Equivalent repacked inputs are accepted. Foreign keys, changed members, other
revisions and already-patched archives are refused. Keep a clean backup.

Windows: extract this whole package, then drag clean mvsc.zip onto
MVSC-DHC-v10.cmd. Keep the filename unchanged.
Python 3.9 or newer on macOS/Linux/Windows, from this extracted folder:
  python3 mvsc_patch.py "/path/to/mvsc.zip" --spec MVSC-DHC-v10.patch.json --out "/path/to/new-output"

The installer creates mvsc_dhc_v10.zip and a .receipt.json beside it. It preserves
the input and refuses an existing output or receipt. Copy the result into a
separate emulator ROM folder and rename that copy to mvsc.zip. A missing key
stays missing. No ROM is downloaded and no network operation is performed.
Python output promotion uses hard links: use a local APFS, ext4 or NTFS volume.
exFAT, FAT and network-share behavior remain unqualified. The Windows CMD uses
a separate promotion path.

Every generated member matches the verified development 59 candidate:

ZIP container hashes can differ with input order, metadata and compression;
use the receipt's member hashes to identify content.

V10 adds a three-page match report with solid black panels, cyan borders and
native gold numbers. VERIFIED POINTS and PARTIAL describe supported event
subtotals. Tracked damage/events are lower bounds. Unsupported or unproven
fields stay N/A; roster/category coverage is incomplete. Full score/leader
comparison remains guarded. Remaining X-Factor slowdown is open, including a
moving-activation publication deadline miss. No no-lag claim is made.

Retained gameplay: choose DHC on STYLE, then CLASSIC or REMIX on RULES.
All styles use three bars. X-Factor is the six-button chord, once per team with
the last living teammate. Combo breaker is exactly LK+MP in supported normal
hitstun and costs one whole bar. Existing exclusions, resurrection rules,
routes, colors and earlier features retain their limits.

Read V10_RELEASE_NOTES_20261008.md and V10_COMMUNITY_TESTING_20261008.md for
measured report behavior, controls, remaining issues and useful test cases.
Included palette notes retain N41, PalMod and individual author credits.

The user authorized this release with scoring/performance work deferred.
Packaging checks passed using Python 3.14.7 and the actual
embedded PowerShell 7.6.5 body on macOS. Native Windows CMD/PowerShell5.1,
Fightcade rollback, physical controllers and broad roster/hardware performance
remain unqualified. Installer verification is separate from those claims.
