fixNES vs Jnes

fixNES is a free, open-source NES emulator for Windows and Linux. It runs NTSC and PAL .nes ROMs and creates .sav files for games that support saving. FDS and QD titles can run when a FDS BIOS named disksys.rom is placed in the same folder, and NSF music files are supported with track changes on the left and right keys. Files can be opened by drag and drop, command-line argument or from ZIP archives. The project lists support for NES mappers and VRC6, VRC7, FDS, MMC5, N163 and Sunsoft 5B audio expansions. Controls are keyboard-only; Windows users can use joy2key for controller input. The standalone build uses supplied scripts and requires freeglut and openal-soft, while a Makefile supports RetroArch core use. The README says the project is not in its most complete or cleanest state. It is licensed under MIT.

Jnes is a free Windows emulator for the original 8-bit Nintendo Entertainment System. Its interface is translated into 20 languages, and it can instantly save game progress. Jnes records gameplay movies for sharing with other Jnes users and converts those recordings to AVI files with video and audio. Compatibility centers on North American and European games, with many popular Japanese games also supported. Cheat support includes Game Genie and Pro Action Replay codes, multiple codes in one entry, and a Cheat Search tool for examining game memory values and creating custom codes. The ROM browser can show game artwork when artwork is available, but artwork is not included with the software. Downloads include Windows version 1.2.1, dated January 15, 2017, and x64 binaries. Netplay and save states are supported. The Android app was removed from Google Play in late 2024, and Android is no longer supported. Freeware terms allow downloading and use but prohibit sale or commercial distribution.
