i see, the person who asked responded to a post i had filtered so i didn't see it
it's not a raw hfs volume, but instead an APM disc image, like for a hdd (like the equivalent of a DOS MBR format, a partition table) with an HFS partition
>/tmp/Marathon Trilogy.toast: Apple Driver Map, blocksize 512, blockcount 1317982, devtype 0, devid 0, driver count 0, contains[@0x200]: Apple Partition Map, map block count 2, start block 1, block count 2, name MRKS, type Apple_partition_map, valid, allocated, readable, contains[@0x400]: Apple Partition Map, map block count 2, start block 9, block count 1317973, name Toast 3.0.4 PPC Partition, type Apple_HFS, valid, allocated, readable

i can loop mount it with losetup and it contains two partitions;
> sudo file -s /dev/loop0p1
/dev/loop0p1: Apple Partition Map, map block count 2, start block 1, block count 2, name MRKS, type Apple_partition_map, valid, allocated, readable
> sudo file -s /dev/loop0p2
/dev/loop0p2: Macintosh HFS data block size: 16384, number of blocks: -24350, volume name: Marathon Trilogy

the mounted volume looks pretty jank but i'm not experienced with HFS
