Really Enjoying The App WORTH THE 5$

I just gotta thanks for creating this emulator through a app. As someone’s who’s always been a console gamer…to go back, and play the old games I fell in love with means a lot to me. I spent 100’s of hours then gaming, and plan to spend 100’s of hours gaming now through this app. 20 years ago I would have never have thought it possible to play PlayStation 1 on a device I can hold in the palm of my hand. I was curious about the Hi Resolution graphics of the emulator compared to original hardware. (My PS1 lid tray I unfortunately found out was busted so I used the PS2). (I compared FF7)The comparison blew my mind there was a significant increase in resolution, and lighting through the emulator. Minor graphical details I easily missed on original hardware could now be seen more clearly. For Gamma I airstream my phone to my smart TV, and play with Bluetooth PlayStation 5 controller. Really hope this team gets the support it deserves, and looking forward towards future emulators. So the question…is this worth a one time 5 dollars purchase for ad free experience? Absolutely, if you plan on using this app regularly the 5 dollars for uninterrupted gaming is more than reasonable. The app runs great, nice hi resolution graphics, and controller support.

Thank you!!! Excellent review! 🙌

Pretty good emulator

Update: Thank you for the option to remove ads. $5 isn’t too bad considering the devs have also been updating this app regularly. I like the direction Gamma is going. Keep it up.

Everything about this emulator seems great: the user interface, ease of adding games, and support for controllers and other options. If you are familiar with the Delta app, you will know your way around Gamma. It’s essentially the same thing. It emulates games well; however, I did encounter a few issues with some games not working or partially working. I’m sure future updates can fix this. The major issue is the ads. Open the app, ad. Open a game, ad. Hang on the opening screen too long, ad. During the ad, it automatically opens the App Store so you can close out of it and continue watching the same ad even longer. The majority of these ads are egregiously long, the kind you can’t get out of until 2 minutes later. Then it will automatically open the App Store to the product and continue the ad even more. This really kills the experience and mood. I suggest getting RetroArch. It plays PS One games with no issues. It’s not as intuitive as Gamma, but if you take the time to learn how to set it up, the experience will be better. Best of all, RetroArch has no ads, so you can play right away. Do better, Gamma.

Great Emulator! (Buttons fixed now 🙂)

This actually works quite well! This emulator runs the games at full speed and has good sound. It lets you push two face buttons at once, and it also has haptic feedback which is helpful because it means I don’t have to look at the buttons when I’m pressing them. The buttons are also positioned so they are easy hit. If it sounds like I’m maybe I’m overfocusing on the controls, that’s because the recent emu boom in the App Store has brought a few emulators that are practically unplayable due to bad controls. This handles it quite well, though. A previous version of the app had trouble with L and R buttons, but they’re fixed now — Thank you!

Note: The free version of this app has ads.
