Adding games to your MicroSD Card

If you open Windows File Explorer (Win key + E) you will see four new drives, two of which are Unnamed, one called ‘boot’ and one called ‘main’. Do not delete, format or change any drives or files on any other drive apart from the drive named ‘main’. This is where you can store your game files.

Open the ‘main’ drive and you will see a folder named ‘roms’ You can go ahead and copy your games here but we recommend keeping things organized

We recommend keeping an organized folder structure if you are planning to add many games. By making folders for each system it allows for easier finding of games and also faster loading times. Make a folder for each of the systems you plan to add games for.

If you have a large number of games for a system, you can organize it further into sub-folders such as A-F, G-L, M-S, T-Z. This makes it faster to load the list of games, and also saves time for you scrolling to get to a game beginning with M for example.

Copy over any files into their respective folders. Once you are done you can insert the Micro SD Card into your BittBoy.

Switch on your BittBoy and it will take a few seconds to boot the menu software. You are now ready to play!
