I should start by clarifying the confusion between the games. Then, explain that the 2018 game isn't on PSP, but if they're trying to run the original God of War on PPSSPP, there are steps to fix it. I'll need to list the common fixes like using specific emulator settings, applying patches, or adjusting configurations. Also, mention legal aspects to remind them not to download illegal ISOs. Since the user asked for an interesting review, maybe highlight the experience of running the game on PPSSPP and the improvements made over time.
