    Hi,

    Can the images not be opened at all or can they be opened but the filenames aren't decoded properly? If they can't be opened at all, then could you please copy the output in File->Debug console after attempting to open an image and then paste it here?

    Hi,

    I downloaded an image to experiment a bit and I got it working somewhat quickly. The latest state of the 'proposed' branch in github has the changes:
    https://github.com/unsound/hfsexplorer/tree/proposed

    This is what I'm getting for MACLIFE44.ISO when selecting the MacJapanese encoding (see screenshot):

    Sorry I have only had time to respond to your earlier message just now.

    That listing looks quite correct! Many thanks.

    As you have found out that particular ISO opens but with incorrect encoding, as do all the others in that collection it seems.

    I have been trying others that have a different problem. Just uploaded one, though I have many more affected like this: https://archive.org/details/maclife-kanjitalk-75

    Screenshot of directory structure as mounted in System 7 is attached.

    Second screenshot shows ISO Buster listing the HFS partition.

    In HFSExplorer: the Partition map is found, then I get "could not open file".

    ISO details:

    MACLIFE-KT75.ISO: Apple Driver Map, blocksize 512, blockcount 660064, devtype 0, devid 0, driver count 0, contains[@0x200]: Apple Partition Map, map block count 2, start block 1, block count 2, name Aplix CDWriter/DiscManager 1.00, type Apple_partition_map, valid, allocated, readable, contains[@0x400]: Apple Partition Map, map block count 2, start block 64, block count 660000, name MACLIFE 1995?N1????, type Apple_HFS, valid, allocated, readable
