This tutorial will show you how to add games (ROMs) to Gamma emulator on your iPhone or iPad. Gamma is a Playstation 1 (PS1 PSX) emulator available on the Apple App Store.
Gamma supports most of the popular PSX ROM formats including:
.BIN/.CUE
.ISO
.IMG
.CHD (added after recent update)
.PBP(added after recent update)
.MDS (added after recent update)
When adding a ROM to Gamma, you need to make sure you are adding a compatible format.
When downloading a PS1 ROM, the files are compressed in the following formats: .ZIP, .7Z, or .RAR. iOS natively supports .ZIP files and you can uncompress the file within any additional app, however, if you downloaded a PS1 ROM and it is a .7Z or .RAR file, then you will need to download an additional app to uncompress the file.
If you have a choice, you should download PS1 ROMs in .CHD format and compressed as a .ZIP file. .BIN/.CUE is a popular ROM format too, however, some ROMs have multiple .BIN files and Gamma emulator can only open one .BIN.
Add ROMs to Gamma Emulator
We found the easiest way to add ROMs to iOS was to download directly to your iPhone/iPad.
1. Find PS1 ROM and download it directly to your device (no links to ROMs will be provided). Make sure the ROM is in a compatible format (.BIN/.CUE, .ISO, .IMG, .CHD, .PBP etc.), otherwise, it will not run on Gamma. Press Download.
2. Press on the download button in the URL field, press Downloads, and press on the magnifying glass icon next to the downloaded file to open the Downloads folder.
OR
You can also access the Downloads folder by opening the Files app and opening the Downloads folder.
3. Extract the file by pressing on the icon of the zip file. A new folder should appear with the ROM files inside.
4. Press on the icon of the ROM file (if it is a .BIN/.CUE, press on the .BIN file) to open it and it should automatically open in Gamma.
That's it. A copy of the ROM will be saved in the Gamma folder so you can actually delete the original ROM files by going back to the Downloads folder, long pressing the file, hitting Delete.

2. Since iOS does not support these compression formats, you will need to download Unzip from the App Store.
3. Open Unzip and press the + button on the top-right corner.
4. Press Files/iCloud Drive.
5. Go to the Downloads folder. Press Browse on the bottom-right corner and go to On My iPhone > Downloads.
6. Select the PS1 ROM.
7. The file will be added to Unzip. Press on the three vertical dots next to the file.
8. Press Extract files(Unzip).
9. Once it is done extracting, there should be a new folder. Open the folder until you see the actual PS1 ROM files.
10. Press on the three vertical dots next to the PSX ROM file (.BIN, .ISO, .IMG, .CHD, .PBP, etc.) and press Send/Open In...
11. Press Gamma. Gamma will open and the ROM will be added.
That's it. A copy of the ROM will be saved in the Gamma folder so you can actually delete the original ROM files by going back to the Unzip and deleting the files and also in the Downloads folder.
