ZX App - ZXDB for Android

Post by Turrican »

Hi all.
A first version of an Android app using the ZXDB API to make searchs.
Very early version that has only General and Magazine Searchs (and a very ugly UI).
The Magazine list shows the cover, number and release year (it takes a time to load the cover from the host site).
General search is cool... I could find a lot of software/books that I didn´t imagine that exists. Try 'Soccer' word.
Download and install the APK (virus free).
Feel free to make comments.

I will upgrade the app soon.

Hi all.
Just to say that the app has grown since then...
It is listed in Google playstore: https://play.google.com/store/apps/deta ... boys.zxapp
Now you can:
- download software (ZX Spectrum and ZX81 files)
- download books (pdf files)
- see YouTube videos (it opens the YouTube app)
- see pictures from softwares and inlays

more to come!

It looks awesome!

My only suggestion for improvement is an option in "General list" to choose if user wants to see a "loading screen" or "running screen" for each title. it's nice to see all loading screens by default, but when an user is searching for some specific game without recalling its name, then showing all running screens will make it much easier to find it.

Hi Einar. That´s good!
I´ll implement in the future.
Thank you for suggestions!

Regards.

PS: is there a way to know which type of inlay I´m getting? Such as: inside, front, back, etc?
Thanks.

As a general rule, if the filename contains "_Front" or "_Back" then it's front or back, otherwise it's a full inlay (front and back together).

This rule should work most of the time, but it's not infallible. I'm planning to implement a better classification in the future, but there are over 10,000 tape inlays in ZXDB so don't expect a better solution any time soon...

How about making it easy for the consumers - add a type and populate type based on _front / _back / full - any errors / exotic cases can be corrected manually afterwards with no pain for the consumers who can start using the normal interface directly.

That's exactly what I'm planning to do.

It seems like a very simple change, so why didn't I do it already? Well, I should probably explain this point...

Each file already has a "filetype" field, that indicates if a certain file is a "Tape image" or a "Cassette inlay", for instance. Instead of a generic "cassette inlay", it will be more useful to have "Front cassette inlay", "Back cassette inlay" and "Full cassette inlay". This way we can avoid creating one more type field that would be only useful in this specific case anyway.

However we currently have 4 filetypes for inlays: "Cassette inlay", "Compilation cassette inlay", "Covertape cassette inlay", "Re-release cassette inlay". Therefore we would to break it down into 12 new filetypes such as "Front covertape cassette inlay", "Front re-release cassette inlay", etc.

However we don't really need these current 4 filetypes. For instance, each file already has a release number, that can be used to distinguish if it's the inlay for an original release or re-release. There's no need to have different filetypes for "Cassette inlay" and "Re-release cassette inlay", this information is redundant.

However the information originally imported from WoS contained some inconsistencies. There are a few cassette inlays from the original publisher classified as "Re-release cassette inlay" and vice-versa. I'm currently working with Pavero to validate and fix these cases. Afterwards I will make the other changes I mentioned.

This case is a good example that we have been working on a lot of ZXDB improvements without any publicity about it! :)

It doesn't make sense to be associating files with release numbers when the release order is incorrect - eg. Thanatos has the Encore inlay as "Re-release cassette inlay (#1)" because the Encore re-release has the wrong year. Correcting the year to 1989 would make it into Re-release #3, but "Re-release cassette inlay (#3)" has already been given to the IBSA inlay.

We have been fixing incorrect release orders already.

However it takes time, because each one of these cases need to be validated one-by-one first. For instance, the database says that Zafi Chip managed to re-release Ikari Warriors about 2 years before it was originally released!

If anyone can help validate and indicate the cases that need to be fixed in our "little bugs" thread, it will help us a lot.

But where has the Zafi Chip year of 1986 come from? It's not from the original WoS entry. Of course they'll need validating one-by-one if you're just going to invent dates rather than add them as "unknown" - whose idea was that?!

Well, the wrong years must have come from somewhere. WoS didn't store re-release dates, but the earliest copy of zxdb I have (17/5/2017) is full of incorrect ones. Is it incorrect WoS data that wasn't displayed, an error in the conversion? There's no documentation to explain it!

Sure, there are still lots of incorrect information to be fixed. That's no surprise, considering that old WoS was a huge database and it's not easy to collect reliable information about titles released decades ago.

If you can download the incremental files mentioned in this post, then run the first 6 files only, you will obtain the oldest version of ZXDB from when it started. It contains all the information imported from old WoS, and some "semi-automatic" bugfixes I embedded into the import procedure (that's about 101 Mb of SQL).

The remaining incremental scripts contain every change we made afterwards in ZXDB. What we have been doing for the last 3 years was fixing wrong information, adding missing data, cataloging MIAs and new titles (that's another 45 Mb of SQL and increasing).

The ZXDB overview is documented here. More detailed information about ZXDB has been explained in hundreds of posts, most of them here, here, here. And if you are interested in even more detail, then every single change ever made in ZXDB has been stored as commented scripts here.

Ah, my apologies then - obviously that date was invented a long time ago. I was of the optimistic belief that re-release years would be the one area that was free from WoS bugs, but sadly no!

The new classification is now available in ZXDB. There are now distinct filetypes for "Cassette inlay", "Cassette inlay - Front" and "Cassette inlay - Back".

Based on the [mention]R-Tape[/mention] idea and using the random function of the [mention]kolbeck[/mention] API, I created a new option in the Zx App to make wallpapers.
Please, it is yet a basic function.

Added "Wallpapers" menu.
When you tap this option, a screen will be opened with a join of a Running Screen and Loading screen. It´s totally random for now. Use back button of your device, then enter again to a new Wallpaper. Take a screenshot of your phone´s screen to use it as wallpaper.

PS: will be available in the "48K Issue 4A" version of the App. It was uploaded recently

Very cool! It would be nice to have a bit more user input, for example tap it to change random, swipe it right to go up an ID, left to go down (or something).
