PC Magazine reports that the "-oid" family of emulators from developer Yong Zhang
(better known as yongzh) has been pulled from Google's Android Market
. These include Nesoid, Snesoid, and Gameboid. From the article: "So what got Zhang the boot? Or, rather, who? Neither Zhang nor Google have commented on the primary source of the complaints against the developer's emulator apps. While most speculate that one of the Big Three are behind the purge–Nintendo, Sony, or Microsoft–there's also speculation that Zhang allegedly violated the open source licenses for projects that parts of his programs were derived from." A piece at Android Police has further mention and some more background
on the legal position of emulator software.
