Street Fighter EX Plus Alpha Recomp

Download v0.2.4-alpha for Windows x64 — online play, player nameplates, and a cumulative Versus scoreboard.

Independent static/hybrid port of Street Fighter EX Plus Alpha for PlayStation, dedicated exclusively to the North American edition SLUS-00548.

The repository contains only source code, configuration, and discovery data necessary to generate the port. It does not contain BIOS, game images, extracted executables, saves, or code generated from these files.

Current features

• Offline gameplay and online Versus: a dedicated launcher for the USA edition SLUS-00548, with online lobby support and rollback synchronization.
• Player names on the HUD: online display names appear on the appropriate player side; offline player names can also be configured.
• Optional player bars: show or hide the nameplates and score boxes using the launcher option. They appear only during Versus gameplay, staying hidden in other modes and selection screens.
• Compact nameplates: up to eight display characters per name, with separate yellow win counters beside the bars.
• Cumulative match scoreboard: each completed match adds one point to its winner. If P1 wins and then P2 wins, the score becomes 1–1. Rematches and character changes preserve the totals.
• Session score resets: returning to mode selection, starting a new session, successfully loading a manual save state, or disconnecting clears the counters. The scoreboard state participates in rollback snapshots to prevent duplicate awards during resimulation.
• Software and OpenGL rendering, with an SDL3-based Windows release.
• Bundled enhancement and presentation resources: 8 MB RAM, CD speed, fast loading, HD textures, PGXP, and bezel options. Included options are not necessarily enabled by default.
• Pinned framework and UI submodules to record the source revisions used by the port.

The maintainer has tested offline gameplay and online matches, including online names, counters, Versus-only HUD visibility, reset on return to mode selection, and synchronized play. This is an alpha release; testing continues across network conditions and gameplay scenarios.

Download and play

The v0.2.4-alpha release provides a portable Windows x64 package:

1. Download and extract exPlusAlpha-20261021-193923.zip into a writable folder.
2. Run exPlusAlpha.exe and select your own supported USA disc image and SCPH1001.BIN BIOS in the launcher.
3. For online play, both players should use the same release and matching supported game content.

The package includes the runtime/launcher, required non-system DLLs, UI assets and fonts, bundled mod resources, license notices, and an integrity manifest. Diagnostic tools, build tools, personal settings, and saves are excluded. Python, CMake, and MSYS2 are not required to play. Game images and BIOS files are not included.

A SHA-256 checksum is provided beside the ZIP. See the full release notes for scoreboard behavior, package contents, and validation details. The packaged runtime version string remains 0.2.0-online-dev; the GitHub release is identified as v0.2.4-alpha.

The project is also listed on PlayPorted.
