Many older games released on optical media employed copy-protection measures that make it very difficult to back them up. This is a listing of the scenes that rip and preserve them, with opinions about the merits of each courtesy of Rom Sheppard.
A work in progress:
| 3DO | TOSEC-ISO | A huge collection of verified dumps, certainly the most detailed 3DO set around ATM. Disc format is simple, so you are losing nothing compared to newer methods. |
| CD32/CDTV | TOSEC-ISO | Again a massive and almost complete collection |
| CD-i | TOSEC-ISO | In terms of regular discs, TOSEC-ISO again has the most exhaustive collection on the net. Regarding movie discs and CD-i Ready, Trurip, since the former were conciously not added to TOSEC-ISO, while the latter is a strange format not supported by other dumping systems. But they still haven’t appeared in public…looks likely to change soon though… |
| PSX | Redump | A huge and almost complete collection. Drawback that the relatively few Libcrypt games need additional files to support them properly, so I’d prefer Trurip for those. |
| PS2 | Redump | Only Redump handles this ATM |
| Gamecube | Redump | Only Redump handles this ATM |
| Xbox | Redump | Only Redump handles this ATM |
| DC | TOSEC-ISO | TOSEC-ISO has the most updated and complete collection of verified dumps. Trurip comes close (most dumps are identical since dumping method for GD-ROMs is the same and I share dumping info between TOSEC-ISO and Trurip, matter of naming choice only there) but it also supports MilCD (unhandled by other methods) and includes a few unverified dumps that won’t be added to TOSEC-ISO until verified. But Trurip tends to lag behind when it comes to new additions to the dat. |
| SegaCD | Trurip | Trurip…high quality and almost complete. |
| Saturn | Redump | Redump has a huge collection in all regions. Trurip might have won for higher overall quality if it wasn’t so lacking in the US set. |
| PCE | Trurip | Trurip all the way |
| PC-FX | Trurip | Trurip all the way |
| NEOGEO*CD | Trurip | Trurip is more accurate and thorough than anybody else. |
| Jaguar CD | Trurip | Trurip all the way |
| PC | Redump | Redump is massive…if you can find it anywhere… |
