eg: Combat School at WoS had a release price of £7.99 and a budget price of £2.99, while the same entry here has a original release price of £7.99, with the £2.99 having moved to the Hit Squad re-release.

Similarly, ACE 2 at WoS has a budget price of £2.99 which has moved on to the Gamebusters re-release in ZXDB.
These prices also came from SPOT/SPEX.

Those are budget prices associated to these specific publishers in SPOT/SPEX. Although WoS used SPOT/SPEX internally, it presented a simplified view of prices on screen, without identifying the publishers for each case.

ZXDB imported all data directly from the internal files of WoS and SPOT/SPEX, so it contains more detailed information than we can see at WoS pages. The drawback is, in ZXDB you can also see any incorrect information that couldn't be seen in the simplified view presented by WoS pages. Hopefully exposing all information will allow us to find out these issues and fix them, so we will end up with an even better, more accurate archive in the end. :)

BTW let me take this opportunity to thank everyone, one more time, for all their contributions! Please notice that our delays in processing all corrections doesn't mean lack of interest, it's just lack of time. But we fully intend to process everything sooner or later!

Also, some prices seems to have been lost in the WoS/ZXDB conversion:
One of Corn Cropper's prices has gone.
The Damned Forest's budget price is missing.
Both prices for Airline have vanished completely!
They are not really gone. If you download any version of ZXDB and look at table "spex_entries", you will find all these prices there.

This table contains the remaining information from SPOT/SPEX that I was not able to "merge" into the main ZXDB tables yet. To be honest I got overloaded with other aspects of ZXDB so I forgot about that! :(

I will get back to this ASAP. Thanks for reminding me about it!

Unfortunately, it's not just titles that were only released on compilations...

The Eye of the Moon was released by Beyond.

Mire Mare was released by Ultimate!

even Bandersnatch! :o
Do they look correct now?
All good!

eg: Duet was only released on the Hit Pak compilation, but apparently it was released in 1987 at £7.95
(where this price comes from is a mystery as it's not on the original WoS entry or the price of the compilation either)
This price came from SPOT/SPEX.

And SPOT/SPEX took this price from Your Sinclair #13. Look at the bottom of this page:

https://spectrumcomputing.co.uk/mag.php ... 34&page=10

It seems the game was announced as a standalone release for £7.95 but never released this way. Therefore this price should be removed. Right?
Wouldn't it be better to change the Elite release from "Original Release" to "Never Released" and keep the intended price information?

A new ZXDB update is available!


EDIT: Internal definition of table "relatedlinks" was changed. I'm sure this won't affect SC but it may affect other sites like ZX Info.

ZXDB adopts the convention (inherited from Martijn's WoS) that only actual releases are stored, for released games. Only if a game was never released, then it stores the publisher that was behind it, although it's not really a "publisher" since it wasn't really "published".

Mixing information about real and imaginary releases for the same game would be confusing IMHO.

If a certain game was intended to be published in a different way, this information can be mentioned as comment if it's considered worthwhile. For instance here.

In the case of Duet, sorry but I don't think the intended release price is an information interesting enough to even deserve a comment.

Column spanish_price wasn't moved. This is typically the release price of the Spanish release of each game, so I'm now working to identify the proper release for each case and assign this value properly. Approximately a thousand games had a spanish price, I have just reassigned about half of them. I will try to sort the rest in the next update.
I just read this. Please don't waste time on this - this information came in from the SPA2 database, and the prices are mapped on a per-release basis there.

I can send you a copy of the current (provisional) state of the SPA2 datase, so that you can work from this. Please pass me an e-mail address so that I can send a database dump to you.

Cheers :)
Thank you!!! I received your material, it will be included in the next update!

Hi @Einar Saukas

Thanks for the update. I think it has broken the RZX section. I will contact you offline.

I'm trying to understand this so I can improve the contributions to the ZXDB, tell me if I'm wrong but I understand that:

Not a publisher:
A game developed in the '80/'90 just for fun, they didn't have any intention to publish the game, but they created an imaginary software house.
Same as above, but they have several titles developed.

A publisher:
A game developed in the '80/'90, they HAD intention to publish the game, but that never happened.
A modern developer that sells physical copies of their games.
A modern developer that distribute digital copies of their games on their own page.
A modern developer that distribute digital copies of their games but does not have any proper Internet webpage or identity.

I wouldn't disappear down that rabbit hole if I were you... a lot of "software houses" were "imaginary" and still published games. :)

Haha, well, yes, that's why I made the distinction about intention. If they had the intention to sell or distribute the game (by mail, etc), even if in the end that doesn't happened, even if the name was a fantasy name, I think we can add the name as a publisher, since it was a commercial endeavor after all, but let's see what other people think about it :)
