Hello !
Well, looking at the screenshot, this is very interesting !
In fact, I can recognize the BACK button on the right. It's the same used in the Gameloft version of Sonic Advance !
So I've got 2 theories about this :
- Either this is an exclusive Chinese release of the Gameloft version.
- Or... It could be a version of its own, which gave a template to Gameloft to release an Android port internationally !
The thing is that despite the Gameloft version been released at the same year as the PuyoSega Android port (2011), it's actually on J2ME phones that Gameloft initially released the game. The Android version of the Gameloft version, on the other hand, is actually released in 2014.
In fact, while extracting the game files of the Gameloft's Android port, it features similar assets to the PuyoSega Android port. But the question was how Gameloft was able to get assets from the PuyoSega port, despite having no involvement. Maybe this obscure port that you just showed me can give us the answer !
