| Save game corrupts at end boss | The "fix" broke memory card mapping | Download a different "scene release" (e.g., from No-Intro verified set) |
| Game runs at 90% speed | CPU decompressing audio in real-time | Overclock emulated PS1 CPU to 150% (DuckStation > Enhancements > Overclock) |
| "Disc 2" won't load after "Disc 1" | Multi-disc PBP not built correctly | Use pbp_tools to split back to separate CHD files |
