Jnes
What it is
Jnes is a free Windows program that emulates the original 8-bit Nintendo Entertainment System. Users can save game progress and record gameplay movies to share with other Jnes users; recordings can also be converted to AVI with video and audio. Cheat support includes Game Genie and Pro Action Replay codes, multiple codes in one entry, and a search feature for examining game memory values and creating custom codes. Compatibility focuses on North American and European games, with support for many popular Japanese games. The ROM browser can display game artwork, though artwork is not included with the software. Its interface is translated into 20 languages. The downloads page lists Windows releases including version 1.2.1, dated January 15, 2017, and x64 binaries. The maker says the Android app was removed from Google Play in late 2024 and Android is no longer supported. Jnes is free to download and use, but its freeware terms prohibit sale or commercial distribution.
