If you want to optimize your retro gaming setup, let me know: What is your PS3 running? (CFW or PS3HEN?) Do you have experience using RetroArch on the PS3?

A is a package format used by the PlayStation 3 to install applications, games, and updates to the internal hard drive. For retro titles like Ocarina of Time , these PKGs are usually "forwarders" or "injected" files. They bundle a Nintendo 64 emulator (like RetroArch or a standalone N64 port) with the game ROM, allowing the game to appear directly on your XMB (XrossMediaBar) like a native PSN title.
