MEGA MAN MAGNETIC SHOCKWAVE v4 — WINDOWS INSTALLER
===================================================

This package contains no ROM data and downloads nothing.

WHAT IT DOES
------------
Mega Man gains Magnetic Shockwave as a ground-only Hyper:

    Quarter-circle back + any two punch buttons

It costs one super level. Version 4 keeps the finished v3 gameplay, meter,
cleanup, and stock-native final-team title behavior, then makes the command
more reliable through the game's native two-punch command parser:

  * LP+MP, LP+HP, or MP+HP may activate when the pair is pressed together;
  * releasing the final BACK direction just before the punch pair is accepted;
  * facing-left and facing-right inputs use the same mirrored timing rules;
  * a single punch, QCF, punch-piano sequence, illegal action state, or a
    second attempt without a new valid motion does not gain a shortcut.

Hyper Mega Man, Rush Drill, Beat Plane, team controls, stock graphics, and
QSound remain on their normal paths. The finish title uses Capcom's native
arcade renderer only when the opposing team is actually defeated.

WHAT YOU NEED
-------------
Windows and your own clean, encrypted Euro-parent mvsc.zip. The installer
accepts only the exact 21-member set containing mvce.03a and mvce.04a.

ZIP timestamps and compression may differ, but all 21 case-sensitive member
names, their canonical order, sizes, and decompressed bytes must be exact.
Phoenix, USA, Japan, expanded, reordered, previously patched (including v3),
mislabeled, extra/missing/duplicate-member, or byte-corrupt archives are
rejected before an output is created. Do not stack standalone installers.

HOW TO RUN IT
-------------
Put the v4 CMD beside mvsc.zip, open PowerShell in that folder, and paste:

    & ".\MVSC-MEGAMAN-MAGNETIC-SHOCKWAVE-v4.cmd" ".\mvsc.zip"

You can also drag mvsc.zip onto the CMD, or use Command Prompt:

    MVSC-MEGAMAN-MAGNETIC-SHOCKWAVE-v4.cmd "mvsc.zip"

No administrator access, Python, Git, 7-Zip, network connection, or extra
PowerShell module is required. The temporary ExecutionPolicy Bypass applies
only to the child PowerShell process launched by the CMD.

OUTPUT
------
The clean input is never opened for writing. New files are written beside it:

    mvsc_magnetic_shockwave_v4.zip
    mvsc_magnetic_shockwave_v4.zip.receipt.json

The receipt records the input/output archive hashes, all 21 member hashes,
eight bounded hooks/data writes, the 1,016-byte payload, and the frozen patch
fingerprint. The installer refuses to overwrite an existing output, receipt,
or temporary file. Move or rename old files yourself before running it again.

DISCORD / TERMINAL NOTE
-----------------------
Attach this ROM-free package or the CMD in Discord. Do not paste the full CMD
body into a message or directly into a terminal: message limits, text
conversion, and newline changes can corrupt it. Recipients should download the
attachment, keep the .cmd extension, and paste only the one-line command above.

VERIFY THE DOWNLOAD
-------------------
On Windows, verify the CMD directly:

    Get-FileHash -Algorithm SHA256 .\MVSC-MEGAMAN-MAGNETIC-SHOCKWAVE-v4.cmd

Expected SHA-256:

    f05663b96546f7de01e22740b29b302c53dcb2eb64a32f536dcbbe6df5ea9191

You can also compare both included files against SHA256SUMS.txt.

ONLINE PLAY / SCOPE
-------------------
This produces a stock-size, Fightcade-oriented modified ROM shape. Modified
program bytes can cause expected CRC warnings or ROM rejection. Both players
need byte-identical patched member bytes and an emulator/session that accepts
them; mismatched bytes can desynchronize play. This is not a promise of
official Fightcade or Capcom support.

This is the standalone Mega Man patch. Use a separately frozen combined
package when Gold War Machine and Mega Man are both wanted in the same ROM.
Do not apply the v3, Gold, or any other standalone CMD to this output.
