This is a complete Nintendo Entertainment System Games collection. This includes every game ever made, as well as Home brews, HDPacks, Screenshots for every game is also included in the Screenshots folder, and a ton more. We have put all Roms and files together within the Mesen emulator, and we have made all setting adjustments needed to simply open and play. You will only need to open Mesen and go to the top of the window, select Options, Preferences, In the Preferences tab select Folders/Files, and then tic the Games box. Then point to the Roms folder that is located in the Mesen emulator. Example: D:\Mesen_Nes\Roms Then simply choose which game folder you would like to use. Example: I like playing the Officially licensed games so I would select the Officially licensed games folder like so D:\Mesen_Nes\Roms\Officially licensed games. Then click Okay, and then choose File at the top left and then select Open from the drop menu or alternatively Use the short cut on the keyboard to load a game (Left CTRL+O) Then enjoy! Look for new Complete Retro Console Systems coming soon!
