Checksums do exist. The Redump project is trying to collect all relevant |
14 |
disc information for every video game ever made, basically. |

The process to generate this information is very specific and requires |
19 |
software that isn't made for Linux unfortunately. But the MD5, CRC32, |
20 |
SHA1 is there which can be usually be checked with `dd /dev/sr0 | |
21 |
sha1sum` for a basic disc. |

PS1 and PS2 games can be checked without special hardware in this case, |
24 |
but for others, specific hardware is required. |

In my case I have a JTAG Xbox 360, so the best way for me to check a |
27 |
game is to have my Xbox 360 dump the disc contents entirely with an app |
28 |
that would not be available on a normal Xbox 360. If this fails at any |
29 |
point it's a bad disc (or it needs cleaning/repair). |
