Javatari vs Íris Emulator

Javatari is a free Atari 2600 emulator designed for the Web. Users can load cartridges in a browser, with ROMs opened from local storage, iCloud, Google Drive, Dropbox or web links. It runs in browsers tested with Chrome, Firefox and Safari, and can be installed as a WebApp on iOS, Android or desktop for offline play. Savestates can be exported and shared. Playback controls include adjustable speed, pause and frame-by-frame advance; display tools include resizing, fullscreen, screen capture and debug modes. Customizable joysticks, joykeys and touch controllers are available, with haptic feedback on mobile. NetPlay lets multiple users connect to and control one virtual console over the internet, although it does not work on Apple iOS because required WebRTC technologies are unavailable there. Performance depends on network quality. A JavaScript API supports ROM loading and console control, and games can be embedded in webpages or launched with a Javatari page link. The project repository identifies the software as licensed under AGPL-3.0.

Íris Emulator is a free, open-source emulator for Atari 2600, Atari Lynx, and Atari Jaguar games on 64-bit Windows 10 or 11. The Atari 2600 core emulates the 6507 CPU and TIA, with NTSC, PAL, and SECAM support and several cartridge mappers. Lynx emulation covers the 65C02, Mikey, and Suzy, with LNX cartridges, HLE boot for homebrew, and optional user-supplied boot ROM support for commercial games. Jaguar support includes .j64 and .jag cartridges, RF Cable and S-Video filters, upscaling to 1080p, and Auto, 4:3, or 16:9 display ratios. The interface offers cover-art browsing, a first-launch wizard, fullscreen mode, remappable keyboard and gamepad controls, and ten save-state slots. VST3 audio processing uses a reorderable chain and master gain. Optional Discord Rich Presence requires the Discord desktop app. ROMs and BIOS files are not included.
