Is there any (easy) way to convert DO to .DSK file format? I'm forced to use Linapple (Retropie) and it only takes .DSK.
"DO" suggests that your image is (already) using DOS sector ordering. There no change besides renaming to whatever.DSK to make Linapple happy. By way of background... DOS sector ordering is the original mapping of physical to logical sectors; sectors 1, 2, 3, etc. are laid out using a skew factor so that they come flying by the read head not in numerical order, but in the order in which DOS is ready to read them. ProDOS changed this order since it always reads two sectors at once, so they're clustered together differently (and due to some code speedups in the core OS, they're skewed differently as well). If a disk was captured in native ProDOS sector order, it would be correctly suffixed with .PO. The naming scheme of "DSK" is ambiguous - it could be either ProDOS or DOS sector ordered. You won't really know unless you inspect it closely and know what to look for; tools like CiderPress and AppleCommander use heuristics to determine which order an image is likely to be. Most newer emulators automatically make the switch to whatever they need as well.
