The Delta app currently supports downloaded versions of countless classics from the NES, SNES, N64 home consoles, as well as Game Boy, Game Boy Color, Game Boy Advance and Nintendo DS handhelds.
An emulator that lets users play thousands of Nintendo games is currently the top free download on the iPhone App Store.
Earlier this week, Apple pulled another Nintendo game emulator app after it was discovered that the app itself was based on another emulator’s code.
Unofficially, emulators like Delta allow users to download countless video game ROMs from internet sites free of charge.
