A free PS1 emulator for iPhone is burning up the App Store charts

It’s called Gamma and offers support for Bluetooth controllers and keyboards.


It’s only been a month since Apple started allowing retro game emulators on the App Store and we already have our second bona-fide hit. The newly-released Gamma is a free PS1 emulator with plenty of bells and whistles for those looking to dive back into the world of blocky polygons. It joins the massively popular Nintendo emulator Delta. We have no idea why these apps keep getting named after the Greek alphabet, as both are made by completely separate devs.

Gamma comes courtesy of developer ZodTTD, which has been in the space nearly since the dawn of the iPhone. The app is primarily for Apple’s smartphone, but there is a dedicated iPad version, which is always nice. Gamma integrates with Bluetooth controllers and keyboards, offering a myriad of input options. It also features customizable on-screen controller skins, but we all know how frustrating it can be to play old-school games with a touchscreen. It’s nice to have the option though.

The app uses Google Drive and Dropbox syncing for backing up game files and save states, and the software will even automatically grab game cover artwork. The whole thing’s actually based on the codebase for Delta, according to reporting by The Verge. As always with emulators, you’ll have to supply the games. To stay on the right side of the law, convert titles that you already own into ROM files.

There’s obviously a mammoth appetite for emulators on the App Store. Delta, the Nintendo emulator, has been a mainstay on the charts since launch and Gamma currently sits at number six, above streamers like Disney+ and Hulu but below TikTok. The reviews, however, are mixed, with many users complaining that the UI needs a refresh and that some third-party controllers, like Backbone devices, cause it to crash. Fixes are likely coming in the near future. In the meantime, Oddworld: Abe’s Oddysee and Crash Team Racing are both begging for a revisit.
