Versions for the following PSX dumps needed...

[Rocknroms]

Ok, I will fix them removing EDC / No EDC from "Version" field and leaving only "EDC" for EDC releases in "Version (datfile)" field until something better will be decided.

PS: I don't want to look like mastermind, but it seems to me that many people use DB fields as custom fields and wrongly tags(ex. Version field for editions, Alt = Rev and so on. All mistakes that should "destroy" DB).

The problem is, we can't be sure in some cases which was first: the No EDC or the EDC..

This EDC thing is a little bit confusing, let's see this rhetorical questions:
-why some discs have EDC and others don't, in discs with the same edition? ( https://redump.info/disc/5513/ - https://redump.info/disc/81/ Platinum ed. in this case)
-why the original release usually don't has EDC and the Platinum releases has (sometimes the time differenece between releases is only 3 or 4 months)?
-why almost all the discs that came out after 1998 have EDC?
Maybe Sony realised that it's better to make the discs with EDC...

There IS no version info on PSX games.. we ASSUME versions based on exe dates, so the one with the earliest exe date gets v1.0 and the newer one v1.1 etc..

But there are exceptions:

-Same EXE date but different edition ( https://redump.info/disc/149/ - https://redump.info/disc/5037/ ...) ,sometimes the game files are the same but they include some promotional trailers or whatever, so it's ok to call, in such cases, edition v1.1 even if the game is unmodified from 1 edition to another (same EXE date)?
-Same EXE date and same edition ( https://redump.info/disc/1755/ - https://redump.info/disc/5470/ ... this shouldn't be (Alt) instead?)
-And why there are a lot of dumps in the DB marked version 1.1 (or 1.0) and there isn't in the DB the version 1.0 (or 1.1) of that game? i mean, even if the existence of such versions is known, i think it's better to wait until someone dumps them, to be sure...

Obviously you never saw a Floyd concert otherwise you would know that pigs CAN fly  lol

I think for most of those dumps that have a version number that there is only 1 version of in the database the reason they have that is because a lot of those games did have another version in the database but they were matrix dumps and the versions never got changed on the other dumps when the matrix dumps got removed...at least I'm aware of 1 game in which that is the reason for. I can't really say why the others are like that.

I thought that this was some interesting points for discussion and no one has nothing more to say?!
After all, all this tags (Alt, EDC, vx.x, etc) have direct influence in the filenames...

By the way, what is a matrix dump?

The issue is that I don't understand if everyone has understood tags, difference between "Version", "Edition" and "Ver. datfile" and relations with no-intro.
After opening this thread I understood that PSX vx.xx are simply conventional, there's no hint to call them that way so as Fireball suggested, as other people wants for other systems (systems that have real vx.xxx, however PSX was not suggested) and as in no-intro convention, it will be better to change them to "Rev x".
Moreover "Alt" is used only if there's nothing else to identify dumps. "EDC" tag could be used as Jackal said if "Rev x" is not possible.
