To access the Quick Menu you can use whatever button is your "Home" button on your controller (PS button on a PlayStation controller or the equivalent on an Xbox controller etc.) or by pressing F1 on your keyboard.Äownload links are at the bottom of the post. If you leave the option set to 100 the custom audio will be too loud and will drown out the sound effects generated by the game. This is equivalent to a real MegaDrive/Genesis using a MegaSD with the CD-DA option set at the default setting of 80, and what all of the MD+ audio packs are balanced around. Once the game is loaded, open the core "Quick Menu" and navigate to "Options", then "Audio", then "CD-DA Volume" and set it to either 65 or 70. IMPORTANT: The last thing we need to do when the game is loaded is to set the CD-DA volume in the core options (outlined in the screenshots below). Now you can load your game in Genesis Plus GX by navigating to the game folder and loading the ROM file.
