This is a list of known PAL PSX games that are missing from the Redump.org database. Please note this list is serial# specific, not title specific.
Sources used:
Note: A "#" on the end of a disc's serial number indicates a software revision about half the time. Some discs in redump only include a "#" version, and ideally versions without # should also be dumped when possible.

 | 
| SLES-02458  |  France  |  Grand Theft Auto 2  |  Barcode: 5026555190268. Different text on front art[54]. Online listings appear to contain SLES-02453 disc [55] (SLES-02458 appears to be a case-only serial number).
 |

| SCES-01324  |  Spain  |  Granstream Saga, The  |  Spanish version/barcode 711719768821 is just a new cover, but disc is standard European release (no new serial).
 | 
| SLES-01814  |    |  Hugo 2  |  Origin of rumor unknown. Region unknown. Hugo 2 was released in many regions, so this possibly exists.
 | 
| SLES-01803  |  M4  |  Monkey Hero  |  Probably originally reported on SonyIndex.com[56]. Take 2 2000 Re-release.
 | 
| SCES-03086  |  France  |  Ms. Pac-Man Maze Madness  |  SCES-03086 serial number is on the case only. SCES-03085 is the disc serial number[57]. Barcode: 711719227922.

 | 
| SCES-03089  |  Spain  |  Ms. Pac-Man Maze Madness  |  SCES-03089 serial number is on the case only. SCES-03085 is the disc serial number[60].
 | 
| SLES-05385  |  Russia  |  O.D.T.  |  An unofficial Russian translation. Fan made serial number. More info[61][62]
 | 
| SCES-01359  |  Italy  |  Pet in TV  |  Redump user Lizard said he bought several copies of the Italian version and just the cover is in Italian, but the disc is not a new serial. Origin of rumor?[63]
 | 
| SCES-01360  |  Spain  |  Pet in TV  |  Spanish release with barcode 711719729723 matches Europe release[64], "SCES-01360" must be a false serial number. Origin of rumor?[65]

 | 
| SLES-03725  |  France  |  Rescue Heroes Molten Menace  |  No proof of existence. Origin of rumor?[66]
 | 
| SLES-00228  |  Germany  |  Resident Evil (with EDC)  |  Supposedly Value Series with EDC. Purchased Value Series ("White Label"), has no EDC. Source [67].
 | 
| SCES-03822  |    |  Stuart Little 2  |  The rom floating around with this serial number on the internet has the same internal serial number and checksums as the Italian redump entry[68].
 | 
| SLES-02829  |  Russia  |  Technomage  |  A hacked translation according to a native Russian speaker that brought it to my attention. Apparently some of this banter clears it up[69]. Fan made serial number.
 | 
| SLES-03169  |  Germany  |  Teletubbies: Spiel mit den Teletubbies  |  [70] Probably doesn't exist.
