Upgrading from 5.50 Prometheus-4 to 6.60 PRO-C2 is a straightforward, low-risk procedure that significantly extends the PSP’s software lifecycle. While 5.50 Prometheus-4 remains historically significant for reviving early 2010s game decryption, 6.60 PRO-C2 offers superior compatibility, stability, and plugin support.
