Roms Psx Pbp ^new^ | 2024 |

No new developments are expected – the format is frozen since ~2007 (PSX2PSP v1.4.2). For preservation, keep original BIN/CUE + convert to PBP only for target devices. | Question | Answer | |-----------------------------------|------------------------------------------| | Best tool to create PBP? | PSX2PSP v1.4.2 (Win) / pop-fe (Linux) | | Max compression? | Level 9 (zlib) – slower decompress | | Multi-disc support? | Yes, via internal disc index | | Lossy audio? | Only if CDDA → ATRAC3 enabled | | Can I reverse PBP to BIN/CUE? | Yes (PBPUnpack or pop-fe --extract) | | Should I use PBP on RetroArch PC? | No – use CHD or BIN/CUE for accuracy | | Should I use PBP on PSP? | Yes – it’s the only direct-load format | If you need a practical guide (step-by-step with screenshots for PSX2PSP) or a shell script to batch-convert your PSX library to PBP while preserving multi-disc structure, let me know.

Multi-disc games: Modern tools (PSX2PSP v1.4.2 or pop-fe) can embed disc 1, disc 2, etc. as separate “discs” inside one PBP – the emulator asks you to swap at runtime. | Feature | BIN/CUE | CHD (lossless) | PBP (lossy possible) | |---------------------------|----------------|----------------|----------------------| | Compression ratio | None | ~30-50% | ~40-60% (zlib) | | Multi-disc single file | No (multiple files) | Yes (M3U + CHD) | Yes (native) | | Metadata embedding | No | No | Yes (icons, title) | | Streaming from storage | Slow (random) | Fast | Moderate | | Emulator support | Universal | Growing (RetroArch, DuckStation) | PSP, Vita, RetroArch, some Android | | Lossy audio possible | No | No | Yes (convert CDDA to ATRAC3) | roms psx pbp

: PBP larger than original BIN. Cause : Embedded uncompressed icons or metadata + poor zlib ratio. Fix : Use pop-fe with --level 9 --max-compression . No new developments are expected – the format

Structure (header followed by data chunks): | PSX2PSP v1

Notably, the (eCFW) runs PBP flawlessly, and the Miyoo Mini / Onion OS includes PBP support via PCSX-ReARMed.

| Index | Chunk ID | Content | |-------|---------------|---------------------------------------------------------------| | 0 | PBP_MAGIC | "PBP" + version byte (usually \0 ) | | 1 | PARAM_SFO | PSP system parameters (title, savedata folder name) | | 2 | ICON0.PNG | 144×80 icon (optional but typical) | | 3 | ICON1.PMF | Animated icon (rare) | | 4 | PIC0.PNG | Background image (480×272 for PSP) | | 5 | PIC1.PNG | Another background (rare) | | 6 | SND0.AT3 | Background audio (ATRAC3) | | 7 | DATA.PSP | (dummy for PSX) — actually points to… | | 8 | DATA.PSAR | The actual PSX disc image (compressed with deflate/zlib) |

Key point: DATA.PSAR contains the raw ISO 9660 + CDDA tracks, compressed. When POPS (PSP emulator) loads a PBP, it decompresses that block on-the-fly.
