ZodTTD, the developer behind a PlayStation emulator for the Android OS, was shut down recently. The software was pulled down off the Android Market. Now another developer follows, possibly pointing to Google's desire to keep things clean and legal on their Market.
Yong Zhang, an Android dev that had several emulators lined up for the OS, has been locked out of the Android Market. Ars says that his applications were removed from the store and his account was terminated by Google without warning. Zhang had a SNES emulator in the works called SNESoid. Some allege that code may have been taken from another popular SNES emulator, snes9x.
I'm sure Android users aren't in a panic yet. There's plenty of emulators to go around for now. I don't know how long that will last, though. With devices like the Xperia Play coming out, it won't make sense for software that permits the use of illegal ROM copies to be available alongside more official offerings.
