The popular emulator, Delta, has undergone a sudden logo change, leaving some users scratching their heads. This unexpected update comes after the emulator received a legal threat from software giant Adobe.

Developed by Riley Testut, Delta has become a go-to option for iOS users seeking to relive classic video games from consoles like the Nintendo Entertainment System (NES) and Game Boy Advance (GBA). The emulator has made its way to Apple devices following a change in Apple’s App Store policies that allowed for emulators. Delta, in particular, allows users to play these games on their iPhones and iPads, offering a taste of retro gaming nostalgia on the go.

The recent logo change stems from a dispute with Adobe. According to reports, Adobe’s legal team contacted Testut, claiming the Delta logo bore a resemblance to its own logo, potentially causing confusion among consumers. While Delta’s logo represented a stylized Greek letter delta (Δ), Adobe argued the similarity could mislead users into believing the apps were connected.

Faced with the potential for legal action, Delta opted to avoid a lengthy battle and promptly changed its logo. The new logo, described as a “broken triangle,” is a clear departure from the previous design. While some users expressed amusement at the somewhat unconventional new icon, the change ensures Delta remains available on the App Store.

The Delta logo dispute is one of the more trivial issues that have been haunting the video game emulation space. There are bigger concerns when it comes to the legality of emulation as a whole when it comes to copyright, particularly because the game files (ROMs) are used to play the games on the emulator. Typically, users are responsible for acquiring these ROMs legally, often by dumping them from their own physical game cartridges.
