OpenEmu

2.2.1
28 January 2020

Open Source game-emulation app (beta).

Overview

OpenEmu is about to change the world of video game emulation, one console at a time... For the first time, the 'It just works' philosophy now extends to open source video game emulation on the Mac. With OpenEmu, it is extremely easy to add, browse, organize and with a compatible gamepad, play those favorite games (ROMs) you already own.

Features
  • Library - One of the standout features of OpenEmu is how it organizes all your games into one unique, unified games library. Watch as backups of the games (ROMs) you already own are gracefully added to their appropriate library and box art is magically added. You can even create your own 'collections' mix and matched from different consoles.
  • Controls and Controllers - Any generic HID compliant USB or Bluetooth game controller should work with OpenEmu out of the box. OpenEmu now automatically maps controls for the following recognized devices in our database:
    • PlayStation Dualshock 3 and Dualshock 4
    • Wiimote and Wii U Pro
    • Xbox 360 and 3rd party (driver required)
    • Sega Saturn USB
    • PS3 Neo Geo Pad USB
    • Logitech series (Dual Action, Rumblepad 2, Gamepad F310/F510/F710)
    • Gravis GamePad Pro
    • Retrolink SNES and N64
    • RetroUSB SNES RetroPort and RetroPad
    • Retrode (SNES)
  • Cores - OpenEmu is modular, and thanks to the work of other great open source projects, it can emulate a wide variety of video game systems (we call them 'cores'). Currently, the following open source emulation projects are used to power OpenEmu:
    • CrabEmu
    • DeSmuME
    • FCEU
    • Gambatte
    • Genesis Plus GX
    • Higan
    • Mednafen
    • NeoPop
    • Nestopia
    • Picodrive
    • Snes9x
    • TwoMbit
    • VisualBoyAdvance

What's new in OpenEmu

Version 2.2.1:
Added
  • BSNES, an accurate SNES emulator with "Display Mode" screen options for HD mode 7 graphics, as the new secondary SNES core plugin. Higan core plugin is now deprecated and will be removed in 6 months.
  • Support for GameCube hybrid analog/digital triggers. - Requires gamepad with true analog triggers, such as the PS4 DualShock 4 or Xbox One S.
  • Automap support for Xbox One S Wireless Controller.
  • Automap support for Retro-Bit Official Sega Genesis/Sega Saturn Bluetooth Controller 8-Button Arcade Pad.
  • Missing GameCube system icon and controller Retina graphics.
Fixed
  • Analog-related input regression introduced in OpenEmu 2.2 where one may be unable to map certain controls or directions may get stuck or not respond in-game.
  • PS4 DualShock 4 delayed inputs and high CPU usage on macOS 10.15 Catalina. - This work arounds a performance issue in IOHIDElementGetParent.
  • Column width when resizing and row highlight system color in List View.
  • Rare crash at startup when dealing with unsupported plugins.
Other
  • Updated localizations.
  • Other bug fixes and performance improvements.

Una pequeña joya que se merece todas las estrellas. En su versión experimental funciona MAME a las mil maravillas. Puedo utilizar dos mandos de PS4 en mi Mac y disfrutar de clásicos. Encima es PRECIOSO, cuidado con todo mimo. ¡Alucinante!

Best of class, by far. Just wish MAME was a key feature. Some work, but the MAME world is flaky at best: http://choccyhobnob.com/articles/demystifying-mame-roms/ Author should lock into a version and focus on it for testing with community.

The Experimental version of OpenEmu has MAME support, which by and large even works very well.

The main problems I see there is a lack of support for analog controllers, which makes many games unplayable. (Unfortunately, the developers seem to be a bit stubborn when asked about adding analog controller support to the MAME core, so I wouldn't expect it to be added any time soon, if at all.)

Nice emu frontend. But I cannot get Mame roms to work. Pity. If anyone can give me some pointers how to get this up and running would be awesome.

You have to use the nightly build to play MAME games in experimental mode. The standard 2.x branch doesn't include MAME in the active emulators.

2.0.2 is unstable. Crashes every time I open preferences. :\

Got stable after leaving it open for a while before going right into preferences. Crash was tied to opening them while it was updating all the cores or something.

A good attempt at consolidating all emulators into one app. The database functionality is excellent. But many of the emulator settings are hidden away which makes playing some games that require tweaking difficult. Beautifully polished and excellent for a free app, but still needs work. Definitely worth looking into however.

Good idea to have the most of the emulators under the same app, but the ROM organization is very limited, there is no way to put the roms under sub-folders (nder the each machine's folder). They also could support the MESS too

Every update is progress, but still unusable as it still won't open compressed rom files other emulators can. My entire genesis collection is in .bin compression format and openemu can't even touch those. It shows games in library but they don't even remotely open. Same problem with GBA. Most of those roms it won't even show in library at all. Again those roms work perfectly in any bannister emulator just fine. It seems a lot more work really needs to be done to ensure this emulator can recognize compressed roms or roms with or without headers.

Either expand them or rename them. With .bin, all you have to do is rename them to .smc. Also, you can get help on their IRC channel almost anytime you need it. The forums are active. Tru uncompressing your library. They won't take up much more space. Then make sure the extension is appropriate. Regarding headers and proper romsets, Bannister's projects work great but haven't been kept current. Romset compatibility changes with the emulators themselves, not just the front end. Make sure, also, you have the right core installed. Otherwise, errors are in the console. A little data massaging with an expansion tool or file-renaming tool and you'll be good to go. For Genesis and GBA, it will even grab most of the artwork.

Does 1.0.3 fix ability to read several rom formats it didn't recognize before? I still have large rom collections it doesn't recognize. Roms can be sort of a mess. compressed, uncompressed. Header, no header. However, my rom collection are all uniform. I ram them all through program to ensure they are all the same. However several systems are hit or miss for me still. Roms that open fine in any other emulator. :\
