|
|
| INTRODUCTION |
|
|
| Due to the ambiguous nature of the current rules, it's time to revise and |
|
|
| add some additional rules. For further clarification check changelog. |
|
|
| |
|
|
| NOTE: The definitions of these keywords are to be interpreted as follows: |
|
|
| MUST=obligatory (release not allowed if rule not followed) |
|
|
| SHOULD=suggested (release allowed if not followed) |
|
|
| CAN+MAY=optional (release allowed if not followed) |
|
|
| |
|
|
+-------------------------------------------------------------------------------+
|
|
| GENERAL |
|
|
| 1.1 Valid filetypes are: .cue, .flac, .jpg, .log, .m3u, .nfo and .sfv. |
|
|
| .1 A release MUST contain an SFV, NFO, and JPG. |
|
|
| .2 A release MAY contain CUE and LOG files from a CD source. |
|
|
| 1.2 Valid media sources are: BLURAY, CD, DVD, HDDVD and VINYL. |
|
|
| .1 A release is not allowed to combine multiple sources. |
|
|
| 1.3 Trackfix is NOT allowed. Bad quality rip requires a repack and MUST |
|
|
| include the ADDITIONAL tag -REPACK- or -RERIP- (rule 4.6). |
|
|
| 1.4 Bad quality rip means: |
|
|
| .1 One or more tracks are incomplete or contain an audio defect such as |
|
|
| skipping, popping, or crackling. Defects that occur during the |
|
|
| production or mastering process of the disc are unavoidable and |
|
|
| cannot be nuked (eg. digital clipping). In such cases, the ripper MAY |
|
|
| include a LOG from EAC proving the defect is due to the disc itself. |
|
|
| .2 The tracks are distorted and constantly clipping (eg. vinyl rips). |
|
|
| .3 The tracks contain constant hissing (eg. vinyl rips). |
|
|
| .4 The tracks are low volume sounding or mono from a stereo source. |
|
|
| 1.5 Directories and filenames have a limit of 128 characters and MUST |
|
|
| contain only valid characters: a-z A-Z 0-9 _ . - () |
|
|
| .1 You MUST replace directories that contain regional characters with |
|
|
| their respective corresponding English alphabet characters when |
|
|
| applicable. |
|
|
| .2 You SHOULD replace tracks that contain regional characters with their |
|
|
| respective corresponding English alphabet characters when applicable. |
|
|
| CD-Tag contains a bug which prevents these regional characters from |
|
|
| displaying properly. |
|
|
| NOTE: Regional characters and their required English character translation |
|
|
| can be found at http://www.immi.gov.au/helptexts/elodgement/elp-h0015. |
|
|
| 1.6 CD releases (including mixed CD) MUST be ripped as separated tracks, |
|
|
| according to the CD's Table of Contents, unless the CD contains only |
|
|
| one track. |
|
|
+-------------------------------------------------------------------------------+
|
|
| DUPES |
|
|
| 2.1 The following dupe rules exist for all sources without exception: |
|
|
| .1 BLURAY does not dupe any other source except HDDVD. |
|
|
| .2 HDDVD does not dupe any other source except BLURAY. |
|
|
| .3 CD does not dupe any other source except BLURAY and HDDVD. |
|
|
| .4 DVD does dupe every other source. |
|
|
| .5 VINYL does dupe every other source. |
|
|
| 2.2 A release MUST have all its audio tracks included in one single release. |
|
|
| Bonus material, such as bonus tracks or bonus discs, or any other subset |
|
|
| of tracks cannot be released by itself. Tracks that contain all silence |
|
|
| MAY be excluded from the release, but note should be made in the NFO. |
|
|
| 2.3 A release MUST not have all its tracks included in ONE previous release. |
|
|
| 2.4 A release MUST not be identical to ANY previous release(s). |
|
|
| 2.5 A multi-disc release MUST not be identical to ANY previous release(s). |
|
|
| 2.6 A release is not a dupe under these conditions: |
|
|
| .1 Previous release has different mastering, even if different quality. |
|
|
| Example: 2014 Remaster vs. 2004 Remaster, Remaster vs. Non-Remaster. |
|
|
| .2 Previous release has different tracklist. |
|
|
| Note: Silence before or after a track resulting in differences of |
|
|
| tracklength is not allowed. |
|
|
| .3 Previous release has a different version of one or more tracks. |
|
|
| Example: Edited, Explicit, Remixed, Live, etc. |
