Cross Fever for XMvsSF — four players

Four humans in X-Men vs. Street Fighter: P1/P3 versus P2/P4, each fighter on its own controller. QCB+HP+HK starts MVC1-style timed Cross Fever with the teammate flying in, under MVC1's meteor sky, with MVC1's TIME gauge, ∞ meter and 1P to 4P markers.

Cross Fever for XMvsSF — four players v2 · Sep 24, 2026

Windows one-file installer: drag your stock X-Men vs. Street Fighter Euro 961004 (xmvsf.zip) onto it. Needs the native CPS-2 four-controller input profile. v2 is the first public XMvsSF four-player build; apply it to the stock ROM, not on top of the earlier v1 preview. Known issues found in play, to be fixed in the next build: the start skips XMvsSF's slide-in team-Hyper portraits and the characters' team-Hyper voices; during the mode a fighter can walk through an opponent; some Hypers (Rogue's, Cammy's, Sabretooth's) can drop their target after the first hit; and stage props and animated stage pieces can show over the meteor sky.

Keep a backup of your stock X-Men vs. Street Fighter Euro xmvsf.zip (961004).
Drag xmvsf.zip onto xmvsf-cross-four-human-v2-preview.cmd; it writes xmvsf-cross-four-human-v2-preview.zip beside it.
Copy that zip to a separate ROM folder as xmvsf.zip and play with the four-controller profile.

Patch-only and hash-gated: it checks your clean parent member by member, never overwrites it, and refuses patched or foreign sets. No ROM, key, save state or emulator is included or downloaded. Preview build: this exact ROM ran in MAME 0.264 with ordinary inputs on the native four-controller wiring. Both teams' Cross was checked update by update, every human fighter's input came from its owner's controller through tags and knockouts, and the markers, TIME gauge, ∞ sign, sky and shadows were checked over about 52,000 frames in ten line-ups covering all 17 selectable characters (the runs set the meter to Level 3 with an analysis write at the start of combat). It is made for four humans: with a player missing on a human side, that player's character has no controller. It passed the installer's own PowerShell and Python test cases. A local FBNeo recorded check, four physical controllers, CPS-2 cabinet wiring, native Windows and Fightcade/GGPO remain untested.

What changed in v2

Four humans on one XMvsSF board: P1 and P3 against P2 and P4. P1 and P2 pick their side's first character, P3 and P4 the second, and each fighter keeps its owner's controller through tags.
QCB+HP+HK starts timed Cross Fever the MVC1 way: the point strikes its call pose with its voice, XMvsSF's own Variable Combination freeze plays, then the partner comes in from behind the point with its own tag-in attack. HP+HK still tags and QCF+HP+HK stays the Variable Combination.
While a side's mode runs: MVC1's meteor sky, MVC1's TIME gauge over that side's Hyper gauge and MVC1's ∞ in place of its level number. The meter shows Level 3, and the mode costs two full bars when it ends (a Level 3 start runs longer and empties the meter).
MVC1's chevrons over every fighter all through combat: 1P, 2P, 3P or 4P for the owner, COM over a CPU fighter.
