ROM Guidelines

Delta Emulator only supports some systems and each one of those systems requires the ROM's file extension (for example: .gba) to be a specific extension in order for Delta to recognize the system to which the ROM belongs. To make things easier, the extension is not case-sensitive.

When importing ROMs into Delta, it is suggested that you import it as a .zip file. When creating the zip file, be sure to include only the ROM; if you zip a folder with the ROM inside, it will fail to import.
