Delta Nintendo Emulator for iOS
I recently discovered the Delta game emulator for iOS, which lets you play vintage Nintendo games. To get started, you need to install three BIOS files: bios7.bin, bios9.bin and firmware.bin. There's a wide selection of classic Nintendo games available for download. For convenience, it's best to save these BIOS files and games to iCloud, then open them in the Delta app. I still own some of my original Nintendo consoles and cartridges, but it's a blast to be able to play a quick game wherever I am.
