Another possibility is using a converter or emulator. For example, there are tools that let you run PS2 games on other hardware, but FIFA 23 isn't a PS2 game. Alternatively, using a PS2 emulator to run a modified version of a FIFA ISO to look or feel like FIFA 23. But again, the data structure and assets would be different, so that would be a massive undertaking.
Wait, maybe the user is referring to the PS2 version of FIFA 23 through a homebrew approach. But I don't know of any such project. There's modded content for older FIFA games on PS2, but not for FIFA 23 itself on PS2. fifa+23+para+ps2+iso+mod+best
But wait, FIFA 23 wasn't released for PS2. The original FIFA games on PS2 went up to maybe FIFA 18 or 19. FIFA 23 is a newer version, and the PS2 is much older hardware. So there's an inconsistency here. The user might be confused or there's a mistake. FIFA 23 is only available on PS4, PS5, Xbox One, Xbox Series X/S, PC, etc. The PS2 is obsolete in terms of hardware for such recent games. Another possibility is using a converter or emulator
