Most ADL games do not have file systems on their floppy disks. As a result, disk images need to be used to play these games in ScummVM. The detection mechanism of the ADL engine uses sector data to recognize these disk images. This means that as long as the base name is the same, any supported floppy image format can be used. For example, if [[Datafiles]] lists MYSTERY.DSK as the disk image name for the game you want to play, you can use either MYSTERY.DSK, MYSTERY.NIB, MYSTERY.WOZ etc. You can find more information on the supported formats below. | Most ADL games do not have file systems on their floppy disks.

Later ADL games and budget releases without copy-protection can probably be transferred with [http://adtpro.com/ ADTPro] and a serial cable. If the game uses the older 13-sector formatting and/or has a copy-protection that prevents ADTPro from seeing all the data, it may be necessary to first use a tool called Saltine's Super Transcopy and then transfer the resulting disks with ADTPro. Note that even if a copy-protected disk is successfully transferred using this method, it probably won't work in an Apple II emulator, but it should work in ScummVM. | Later ADL games and budget releases without copy-protection can probably be transferred with [http://adtpro.com/ ADTPro] and a serial cable.

=== Using Applesauce and a Disk II === | |||
Using this method, .WOZ disk images can be created. See [https://applesaucefdc.com/] for more information. | |||
=== Using KryoFlux and a PC 5.25" disk drive === | |||
A major hurdle with this method is that a modern PC disk drive requires a ''flippy mod'' to read the other side of a dual-sided disk. There are some workarounds for doing this with an unmodified disk drive, but they all involve damaging the sleeve of the original floppy. After obtaining stream files of the disk, [https://atariage.com/forums/topic/231835-a8rawconv-a-new-raw-disk-conversion-utility/ a8rawconv] can be used to create a .NIB image. There do not appear to be any tools to create a .WOZ image from stream files at this time. | |||
