: Most users prefer installing the RetroArch PKG because it supports multiple "cores" (emulators), including various versions of MAME and FinalBurn Neo.

Most users prefer RetroArch rather than a standalone MAME package. RetroArch is a frontend that includes "cores" (emulators). It includes a MAME core (specifically MAME 2003 or 2010).

: In the PS3 ecosystem, a PKG is an installation file similar to an .exe or .dmg. It is the standard format for homebrew apps, allowing for easy installation via the console's "Package Manager". Hardware Requirement : These emulators require a modded console running Custom Firmware (CFW)

Because MAME is open-source, developers have stripped down the core to run efficiently on the PS3’s 256MB of RAM—one of the main challenges of arcade emulation on this console.
