About

A static recompilation of the PS1 version of Street Fighter EX2 Plus (SLUS-01105) built on psxrecomp and recomp-ui. The README's info table lists two players, USA region, publisher Capcom and year 1999, and its status section says it is playable end to end, with boot, 60 Hz gameplay, gamepad input and in-game reset to Mode Select working.

Getting started

You need your own legal SCPH-1001 (US) BIOS dump, because the title does not work with OpenBIOS, plus your own disc image (.cue/.bin). The README says the controller must be in digital mode, since analog mode makes the game ignore input, and vsync is turned off so the 59.94 Hz pacer controls the frame rate on high-refresh monitors.

Known issues & limitations

Use digital mode; analog / DualShock mode makes the game ignore input.
Multitap should be off for a normal 1v1 game.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (PlayStation version).

You need your own legal disc image in .cue / .bin format.
You must own the original game.

How to install

Run it standalone using the release zip and the built-in recomp-ui Generate & Build flow.
On first run, point the wizard or bios.cfg to your own legal BIOS dump.

Summarised from the project's README.
