So for games that require you to use the analog stick, games that came out after the release of the dual shock controller, have issues where the amount that you are returning or inputting, will fluctuate!!! This is highly annoying, especially in racing games!!! Case in point, Need for Speed High Stakes steers, the car with the analogic only as the digital pad is assigned to things like turning on your headlights or changing other settings... Steering the car, the analog stick is very hit or miss and you will find yourself swerving all over the road in a game that you are very good at!?!? PLEASE FIX!!! I thought it was my controller at first, but I have now tested every controller against every single game in emulator and it only happens in Gamma!!! PLEASE FIX ANALOG STICK LINEARITY/SENSITIVITY!?

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.

Getting there.

The app is staring to come together for sure but its still missing some features that are on Duckstation and Medafin. The one feature I would love to see more than anything is retroachievement support. While Beetle on RetroArch has support it’s missing support for PBP files for unlocking them. Duckstation has it and I’m hoping that Gamma will also. I also purchased it to support the developer and other should too if they want to see this grow.
