HVSC SID Playtime Database ?
I am currently coding something Sid related Tool for PC and was wondering if there exists a Database (csv,xml,or whatever) that contains the default Sid Subtune Playtimes.
At the Moment i use Siddiag to recieve the Sidtimes, but this very annoying and time intense. If there would be a DB-File where i could search with the MD5 of the Sid that would speed up Time detecting a lot.
Anyone knows about the existance of this or something simmilar ? |

There's a lot of discussion about calculating the MD5 in this thread (at the bottom): Track Times in SID files? |

I already saw that thread, and also understand the complains about md5 beeing more acurate when Playing a Sid.
But for my current Project i need the md5 created on the Filecontent (summing Bytes), which is completely different. I just wanted that because i didnt want to start siddiag all the time for each single Sid i want to have in my Database.
Nevermind, i have created the md5 Database with the Layout i wanted myself, instead of complaining it isnt there, so i dont have to lick anybodys Balls or wait Days/Weeks until it`s done (if ever)
And for the ones that are not found due better or older Rips, Header Change or whatever i index them with siddiag on runtime.
But thanks for guiding into the right Direction :-) |

lol ? probably you dont expect there are people not coding c , i am not into c at all.
but instead of porting that code to my project i decided to use 17 lines of code to merge sidlenghts.txt and my previous created hvsc67.md5 into a new songlength.md5
as previously said, thanks for guiding into the right Direction :-) |

Again, in case the message didn't get through yet:
The MD5 in Songlengths.txt is based on the .sid file contents, not on the playback result. |

The MD5 hashes in the Songlengths.txt file are based on the content but not on the full content. You need to know which fields in the SID header needs to be included in the MD5 calculation and how to handle them and in which order, in order to get the right MD5 hash.
The MD5 calculation was done in the time that we had to compare a lot of SIDs against the HVSC collection to filter out double entries. There was a need that SIDs with a different title, author or released field would produce the same hash. The same MD5 calculation was used for the Songlengths database since the tooling was already there.
For a lot of people the calculation is confusing and unclear. Having the MD5 hash based on the full content makes more sense and we're considering it for changing it since there is no need for having this kind of MD5 hash for the songlengths database. Changing it means also that current applications and tools need to be updated. |
