Understanding Fragmentation & Repair
Why fragmentation matters
The PS2 reads files by physical location on disk. Fragmented files can cause load stutters or failures on real hardware, even when a PC/emulator plays them fine.

Platform note: verifiability of physical fragmentation can differ by platform and environment. When a result can’t be confirmed, OPL Forge reports it as

Repair
Repair runs as a transactional operation with a journal, staging area, and automatic rollback if anything goes wrong, so a failed repair never leaves your library in a worse state than before.
