Module iso 

Minimal ISO9660 lookup: find a file in the disc’s root directory.

Enough for a movie player to open MOVIE.STR by name instead of by a baked LBA: read the primary volume descriptor (LBA 16), take the root directory extent from it, then scan that directory’s records.

Constants

PVD_LBA

LBA of the primary volume descriptor.

Functions

find_in_directory

Search one directory sector for name (compared without the ;1 version suffix, ASCII case-insensitive). Returns (lba, size_bytes).

root_directory

Root directory (lba, size_bytes) from the primary volume descriptor.
