It represents a specific moment—the peak of the COVID-19 lockdowns in 2021—when thousands of retro gamers, stuck at home, turned to arcade emulation for escape. It represents the ingenuity of crackers who decapped physical chips to preserve code that Sega had long abandoned. And it represents the fragile ecosystem of emulators, where one small .bin file named after a circuit board location stands between you and a perfect game of Marvel vs. Capcom 2 .

The answer lies in . Flycast excels at speed and RetroArch integration, but it sometimes uses high-level emulation (HLE) to skip the authentic SH-4 CPU and PowerVR pipeline.
