(those on current official firmware), this entire ecosystem is useless and potentially dangerous. If you have an exploited console (FW 9.00 or lower), invest time in learning to use a proper download manager and verifying sources. If you have a modern PS4, ignore this entirely—stick to the PlayStation Store.
⭐⭐⭐⭐ (4/5) Deducting one star for the steep learning curve and persistent malware risks.
