Emulation is the process of simulating hardware of one machine on another, so in our case, playing CPS1, CPS2, Neo Geo, Sega Genesis etc. games on your mobile device or PC/MAC.
An emulator is the program / app / software that simulates the machine you wish to run, so in our case, an emulator allows you to run CPS1, CPS2, Genesis, Sega, Neo Geo etc. game ROM / images on your Mobile, PC or Mac.
ROM stands for Read Only Memory. It is the image of the actual game; for example: Cadillacs and Dinosaurs. This is basically a file that has been converted from a game cartridge or CD so that you can run it on your computer.
Certain emulators run certain ROMs better, depending on their compatibility, so try running the ROM with different emulators. If the ROM still doesn't work, its most likely that its corrupt (not playable).
Some games are protected by the ESA and are illegal to distribute. We fully support the gaming industry, so if you really like those games, buy them!
A BIOS file is a key component of retro game emulators that allows them to emulate the hardware of the original gaming console. The BIOS (Basic Input/Output System) is a firmware that runs on the console's hardware and is responsible for initializing the hardware components, performing some basic system checks, and loading the operating system or game. When you use a retro game emulator, you need to obtain a copy of the console's BIOS file and place it in the appropriate directory of the emulator software. The BIOS file is necessary to enable the emulator to accurately emulate the console's hardware, and to ensure that games are playable on the emulator.
