You might ask: “Why 6.60 and not 6.61?” The answer is . While 6.61 is newer, 99.9% of homebrew, plugins, and cheats are developed for 6.60 . PRO-C2 for 6.61 exists, but many tools (including Chronoswitch and some version spoofers) work better on 6.60. Unless you need to play a specific game that requires 6.61 (extremely rare), stick with 6.60. psp 352 m33 upgrade to 660
