The search for such files is ill-advised, as available downloads are either mislabeled legacy games or malicious software. Users seeking to play Forza Horizon 4 must utilize the platforms for which the software was natively developed (Xbox consoles or Windows PCs).
The PPSSPP emulator is designed to run software originally created for the Sony PSP. Because Forza Horizon 4 requires modern hardware—minimum 8GB RAM and a DirectX 12 compatible GPU—it is technically impossible for the PSP hardware or its emulator to run the actual game.
