Some European PS1 games have LibCrypt protection that interacts badly with PBP compression.
To patch a game originally in PBP format, you must first extract the raw game data (ISO or BIN/CUE) because most patching tools cannot read the compressed PBP wrapper. Recommended Tool: PSX2PSP convert pbp to iso patched

: Extracting a PBP usually loses the custom icons and background music (XMB assets) unless you manually save them during the unpacking process. Use a Patcher : Most patches use xdelta or PPF
To convert a (EBOOT) file back to an ISO (typically to apply a translation or gameplay patch), you need to extract the raw data first. You cannot patch a PBP file directly. 🛠️ Required Tools
