Here’s a concise review of the process and considerations around downloading file systems for PS2 Matrix OPL (Open PS2 Loader).
The Advanced Partition Allocation (APA) is a partitioning system used by the PS2 HDD. It organizes the drive into partitions (e.g., +OPL, __common, PP.SLUS-12345.00). APA uses a linked list of partition descriptors stored in the first few sectors of the drive.
