Creator Of iPhone Game Boy Emulator Says Nintendo Made Him Pull It

For a few months now, an app called GBA4iOS has allowed iPhone users to take advantage of a system loophole in order to play Game Boy and Game Boy Advance games without jailbreaking their phones.

But if you didn't get the app before yesterday, you might be out of luck—Nintendo has filed a takedown notice, according to Riley Testut, the high-school student who created the emulator.

You can no longer download GBA4iOS—which was hosted on the software database Github until yesterday afternoon—but if you've already got the app, Testut says it'll continue working.
