How about this folks: I am the creator of XtenDS too (damn just can’t escape my homebrew wrath).
Yeah, XtenDS was my first IDE, but I got tired of the name, which didn’t rank in Google (and wasn’t relevant to what the software did). So I gave it up, copied the source and worked on it till now; we have DS Game Maker.
And I don’t know where you read that XtenDS made 3D games or was even comparable to DS Game Maker. The website for it isn’t up, and the last version before retirement about a year ago was V8.
