MSH TAG for Marvel Super Heroes

Two-on-two tag teams for arcade Marvel Super Heroes (1995), in the style of Marvel vs. Capcom: Infinite: two picks per side in six colors each, HP+HK tags that fly in and carry a combo, Counter Switch out of a combo, crossover counters, push blocks, snapbacks that knock the point off the screen, double teams with both heroes on screen under Marvel vs. Capcom's meteor sky (from your own mvsc.zip), team supers and hyper tags, two same-size life bars and both heroes' faces per side, red life that heals on the bench, a TIME bar along the bottom in double teams, KO hand-offs and a partner for every CPU opponent. For the 951024 sets, the msh set Fightcade plays included.

MSH TAG for Marvel Super Heroes v1.2 · Oct 1, 2026

Windows one-file installer: drag your clean Marvel Super Heroes ZIP (msh, mshu, msha, mshjr1 or mshud, the 951024 revision) onto it, or put the ZIP beside it and double-click. It writes <set>_tag_v1.2.zip beside your ZIP (msh_tag_v1.2.zip for msh) and never changes the original. With your clean mvsc.zip (Marvel vs. Capcom) next to your ZIP, or dropped on it too, double teams get Marvel vs. Capcom's meteor sky, read from your file; without it the stage stays. On macOS or Linux, use the Python patcher in the patch package (--mvc names the Marvel vs. Capcom ZIP). The key file comes from your ZIP, as Fightcade's and MAME's have it inside; mshud's phoenix.key is written if it's missing. Patch the clean ZIP, not an earlier patched output. Four players: the MSH TAG four-player download. v1.2 makes automatic tag-entry attacks blockable standing or crouching and fixes Hulk’s confirmed crouching HP followup. The patch package includes the independent tester checklist.

Keep a backup of your clean ZIP.
Drag it onto msh-tag-v1.2-preview.cmd (with your clean mvsc.zip beside it for the double team sky); it writes msh_tag_v1.2.zip (named after your set) beside it.
Fightcade: back up emulator/fbneo/ROMs/msh.zip, then put msh_tag_v1.2.zip in its place as msh.zip. MAME: copy it to a separate ROM folder under the set's name and start it from a command prompt, or with PLAY MSH TAG MAME.cmd.

Patch-only and hash-gated: complete member identities, every replacement site and native routine/table checks in the correct DATA or opcode view. All five real clean sets pass both installers (10 cases); Python and the exact installer PowerShell body on PowerShell 7/macOS write identical members, and 19/19 fixture tests pass including the optional sky. Every one of the 43 two-player / 45 four-player dependency guards refuses a modified input; eight negative controls produce no output. Originals remain unchanged. No game ROMs or retail keys are distributed. On the final Phoenix two-player build, 220 Hulk cases and 25 explicit guard expectations across 27 two/four-player probes pass (two roster whiffs excluded), alongside nine quantitative regressions and visual K.O./DOUBLE K.O. checks. These are bounded local diagnostics. Independent Windows/Fightcade installation, Windows PowerShell 5.1, cmd.exe/drag-and-drop, the Windows core on Windows, RetroArch UI and online play, four physical controllers and real hardware remain unverified. USA/Asia/Japan have installer coverage only. No new long-session soak is claimed. See TESTER_CHECKLIST.txt in every package.

What changed in v1.2

v1.2: automatic tag-entry attacks can be blocked standing or crouching. The automatic entry move uses this rule; ordinary jumping attacks keep their native overhead behavior.
In two-player mode, holding HP+HK to tag no longer hands those held attack buttons to the incoming hero. Four-player partners keep their own independent pad input.
Hulk’s crouching HP followup reaches small and crouching opponents after the first strike hits or is blocked. Only that confirmed followup uses the adjusted box; a first strike that whiffs keeps the original followup. Move timing, damage and reaction remain unchanged.
The v1.1 fixes remain: rounds, arcade progression, tags and character flags, colors, gem inventory and carry, and the K.O. call. Patch your clean original ZIP again.

The key file comes from your ZIP, as Fightcade's and MAME's have it inside; mshud's phoenix.key is written if it's missing. Patch the clean ZIP, not a v1 output. Four players: the MSH TAG four-player download.
- v1.1: fixes for what testers found on the September 28 stream, and two more the fuzzing found. Patch your clean original ZIP, not a v1 output.
- The first game after power-on plays one round too. v1 played it best of three, and a knocked-out partner stayed out in round 2. A draw's final round starts both teams whole.
- Arcade: a CPU team you beat stays beaten. v1 marked whoever was on point at the knockout, often the partner, so the same team could come back as the next match.
- Daily Bugle: the reflections in the windows keep the stage's own colors (v1 painted them in the partner's colors). Captain America's shield keeps his colors when he tags back in (v1: the last partner's).
- A tag no longer hands the leaving hero's projectiles and effects to the one coming in, and a hero that tags in no longer inherits the first one's character flags. In v1 both could crash the game: Blackheart's Inferno with a gem, Captain America's shield, Juggernaut teamed with Iron Man.
- A hero knocked out while it leaves is out: v1 benched it with no health and the team could tag it back in. A partner has no Infinity Gems of its own: in v1 its empty slots read as the Power Gem, which it could use without end.
- An Infinity Gem that's running keeps going through a tag: the hero coming in gets it (v1 ended it, so a Soul Gem stopped healing). DOUBLE K.O. only when both teams are out: v1 called it when a hero went down and its partner, dropping in, knocked out the other team's last one.

Download MSH TAG v1 (retail installer fix)
v1 · released Sep 27, 2026 · Previous. September 27 correction: the old installer wrongly rejected clean retail ROMs at $005E38 (life bar tiles). Download this version again and patch your clean original; the table reads and checks are corrected, with all ROM identity checks retained. Windows one-file installer: drag your clean Marvel Super Heroes ZIP (msh, mshu, msha, mshjr1 or mshud, the 951024 revision) onto it, or put the ZIP beside it and double-click. It writes <set>_tag_v1.zip beside your ZIP (msh_tag_v1.zip for msh) and never changes the original. With your clean mvsc.zip (Marvel vs. Capcom) next to your ZIP, or dropped on it too, double teams get Marvel vs. Capcom's meteor sky, read from your file; without it the stage stays. On macOS or Linux, use the Python patcher in the patch package (--mvc names the Marvel vs. Capcom ZIP). The key file comes from your ZIP, as Fightcade's and MAME's have it inside; mshud's phoenix.key is written if it's missing. Patch the clean ZIP, not an earlier output. Four players: the MSH TAG four-player download.
- September 27 retail installer correction: fixes the false $005E38 life-bar-table refusal on supported clean 951024 sets and the associated runtime table reads; preserves all member and hook checks. Re-download and patch a clean original.
- First release. Two picks per side, and the confirm button picks the colors: LP is the game's own, LK, MP, HP, MK and HK are Marvel vs. Capcom 2's.
- HP+HK tags: the partner flies in at the opponent with its jumping attack while your hero finishes its move, so a tag carries a combo; a normal or special that hit or was blocked cancels into it.
- Counter Switch (HP+HK while being hit, 2 levels, or your red life and a tenth of your life), crossover counter (B, DB, D + HP+HK while blocking, 1 level), push block (LP+MP+HP while blocking, free), snapback (QCF + MP+MK, 1 level: the point is knocked off the screen), double team (QCB + HP+HK, 2 levels), team super (QCF + HP+HK, 2 levels) and hyper tag (HP+HK during a super, 1 more level).
- Two life bars per side, each the size of the game's own, and both heroes' faces; the bench is darker gold with a gray name and a darker face; red life heals on the bench. The gauges sit under the bars and stop at Level 3; in a double team the gauge reads infinity and a TIME bar runs along the bottom.
- Double teams fight under Marvel vs. Capcom's meteor sky when you install with your clean mvsc.zip: the installer reads it from your file.
- KO hand-off: the partner drops in, untouchable until it lands. CPU opponents bring partners and tag.
- Current validation: all five real supported sets pass both installers; Euro and Phoenix builds pass bounded native boot/selection/tag/HUD checks in two- and four-player modes. Broader v1 feature footage predates this correction; Windows and online acceptance remain unverified.
