Files Settings In this pannel you can change some parameters about the files opened by the emulator.             File History Determines the number of files that will be shown in the file history for cartridges, disks, and cassettes. Valid values are 0 to 30 entries.        Drag and Drop If you use the drag and drop of a file (rom image, disk image) to the emulator, the file will be loaded generally in slot 1 or drive A. You can change this behaviour in this menu by selecting the slot 2 for the rom images or the drive B for the disk images.        Open Rom Dialog Determines the default mapper type in the open rom dialog for the rom images for which there is no crc32 code in the rom database
