MVSC-DHC-v9.2.2 — prepared community-testing candidate

This patch-only package contains no game archive, key, emulator or save state.
Supply clean encrypted Marvel vs. Capcom Euro 980123 (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-v9.2.2.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-v9.2.2.cmd.
Python 3.9 or newer on macOS/Linux/Windows, from this extracted folder:
  python3 mvsc_patch.py "/path/to/mvsc.zip" --spec MVSC-DHC-v9.2.2.patch.json --out "/path/to/new-output"

Python output publication uses os.link. Install on a local filesystem that
supports hard links, such as APFS, ext4 or NTFS. exFAT, FAT and network-share
behavior remain unqualified. The Windows CMD has a separate promotion path.

The installer writes mvsc_dhc_v9.2.2.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 978b27246ccf711c2bec22dcb7601c69bb237326c199c777461b5ee64a6fea07; 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 focused update corrects fictional-color portrait mapping for Orange
Hulk, Red Venom and Gold War Machine and reduces work when X-Factor is inactive.
Original P/K portrait colors, all body colors, audio, graphics and key stay
exact. Active-feature behavior is checked against the previous machine paths.
The included qualification separates data/machine checks from native visual
and performance checks; the reported super slowdown is not claimed resolved
without a matched native comparison. Read V922_COMMUNITY_TESTING_20261004.md.

Original stock throw behavior is retained. No optional stock-grab compatibility
variant is included. DHC changes and nine colors apply to REMIX; ARCADE retains
native cancel rules and its original P/K color selection.

Prepared on 2026-10-04. Local packaging checks passed with Python 3.14.7
and the actual embedded PowerShell 7.6.5 body on macOS. Native Windows CMD,
Windows PowerShell 5.1 and Fightcade/rollback acceptance remain unverified.
Packaging preparation does not authorize publication or establish complete
gameplay acceptance. This package is marked prepared, releaseAccepted:false.
Read the included combined qualification and release notes for measured repairs,
retained behavior and open reports. Component-specific checks do not establish
historical sound root causes or broad audible/Windows/rollback correctness.

N41's native palette/layout research is credited in the included palette notes.
PalMod and individual indexed-palette authors retain their documented credits.
