SuperTuxKart Apps for Mobile Devices - GPL violations

Hi all,

If you were on IRC, you might have read it already, that there are unofficial STK Ports for Mobile Devices.

They are called

"Super Kart 3D" - Available on iOS and Android - price: free (with in app purchases)
"SuperTuxKart" - currently only Android - price: 0,72€, AU$: 1.02; 0.99CHF; 0.99US$

Both are from the developer "Playstarz Inc.".

If you have already bought "SuperTuxKart", send us a copy, to investigate, if there are GPL violations!

Please do not buy/install these games! We are investigating for copyright infringements.

Best regards,
supermat

Oo omg !
It's not really surprised as the game is getting better every day thanks to the work of everybody :)
In my opinion if you look at Super Kart 3D, the dev's are trolling by keeping the name of sara :oops:

What we can do is to dislike youtube video of these dev and signal this is a copy

:!: Be careful, do not click several times on these video; the goal is not to increase the number of views.

We have to make Supertuxkart be known by as much people as possible :cool:
Stk will always be a length ahead of those other games :)

Hi,

I'm downloading .apk file from some site in China. I'll look at data file to see if it uses any code/data from SuperTuxKart.

[EDIT] I found "SuperTuxKart" string in "Super Kart 3D" binary file!!!1!!1!! (libSuperKart.so)

* The data files is packed in res.pak, compression method not analyzed (possibly uncompressed) but checked file list there are some files obviously copied from SuperTuxKart (e.g. data/fonts/AR_PL_SungtiL_GB0.png data/fonts/StkFont.xml data/models/bubblegum-nolok.b3d data/po/supertuxkart.pot)

* I feel that this is done by some Chinese people because I found that some added images has Chinese edition (e.g. data/gui/setting_control_touch_cn.png) and there is only a Simplified Chinese translation file (data/po/zh_CN.po)

@acme_pjz: Thank you, but we already did that. :)

Totoplus62 submitted already an license violation notification to the stores, because data/models/swatter-icon.png is violating CC-BY-SA (I think).
Totoplus62 - please notify us, if you contacted the dev (not) successfully.

Best regards,

No answer, i hope it was well sent as i'm not at home for a moment.
Then i'm sure there are others unmodified game assets that were stolen.
What about the panda we can see several time in their trailer ? Is it protected ? Or the traffic_light_yellow.jpg texture at the beginning of the race ?

@totoplus62: I looked at some of the files, but I think, the JPGs are compressed. So I can't look at the hashes. If you are on Linux and you have the data files from Super Kart you can look at the hashes.

Open Terminal, enter "md5 " and the filename. If it's the same result for the original STK files and the ones from super Kart, it's stolen.

Hi all,

Good News: seems that the apps for Android are taken down :).
Bad News: Apple did not respond :(.

Yes, google reacted very quick (4 days). Apple didn't send a confirmation or any updates. So I prepared another longer document to explicitly list most of the violations, but when I tried to submit it, the ios application was not found anymore - it must have been taken down in between.

So, we won ;)

Cheers,
