MAME(Opens in a new window) is the best way to play arcade games on your PC, but it's not particularly user-friendly.

Your best bet is to activate MAME through the command line, no matter how adverse to coding you might be, or download a compatible third-party front end.
As an emulator, MAME allows you to play games from many Capcom, Namco, Neo Geo, and Sega arcade systems, plus some older home consoles and personal computers. MAME even offers a page with ROMs that are safe to download, if you'd prefer to avoid any legal gray areas. Remember that not all ROMs will play perfectly, so developers also offer an FAQ page(Opens in a new window) for game-specific issues you might come across.
PPSSPP(Opens in a new window) is the emulator you turn to for playing PlayStation Portable games on a computer or mobile device. It's a free program, but you can also purchase PPSSPP Gold(Opens in a new window) to support the developers.
