GoKawiilPS5X emulator runs on Xbox Series X but is capped at 5GB memory
A new emulator called PS5X lets Xbox Series X hardware run PlayStation 5 games, but only through Microsoft's Developer Mode, which restricts games to 5GB of memory versus the 13.5GB available to retail Xbox titles. The cap only lifts when software runs via the Visual Studio debugger, a developer-testing setup, and consoles in Developer Mode cannot load retail games until switched back. Microsoft banned emulators from retail Xbox mode in 2023 and has reportedly suspended players for 15 days for circumventing that policy.
