PlayStation Portable emulator PPSSPP turned one this week, and to celebrate the developers released version 0.9.5. This adds post-processing shaders and fixes loads of bugs and emulation issues. Head over to the PPSSPP news page for more details, and download an unofficial Mac binary here (requires SDL).

Open-source virtualisation tool VirtualBox got both a major and a minor update in October. Version 4.3.0 added USB touch device emulation, SCSI CD-ROM emulation, and loads of other things, while 4.3.2 fixed bugs in the virtual machine, GUI, and more. See the changelog for more details.

Sappharad was on the forums recently updating us on the progress of his Mac port of multi-system tool-assisted-speedruns-focused emulator Bizhawk. The latest build is 1.5.2, with recent additions including TI-83 support and loads of bug fixes. There’s still no native user interface, but the main Bizhawk team is refactoring the code to make it easier for someone to do this (if anyone’s up for the task). See the MacScene forum thread here, grab the download here, or check out the Bizhawk Google Code page for more details.

ScummVM celebrated its 12th birthday in style with a super cool visualisation (embedded below) of the history of its codebase. Even if you don’t understand the slightest thing about coding and classes, this will give you a great feel for the scale of the project and the 58,000+ commits made by hundreds of coders. If you’re looking for a more narrative-based history, head over to Ars Technica for my big feature on the project from last year.

You can get it from the Dolphin download page, while the announcement post is here.

After a long period (three years) without an official release, Sony PlayStation emulator PCSX-Reloaded has been updated to version 1.9.93 beta. People who’ve been using SpeedofMac/ConsoleEmu’s unofficial builds won’t notice much of a difference, but it’s a huge improvement over 1.9.92. See the release notes here for details.

Continue reading for additional updates, including new versions of Mednafen, Q-emuLator, zxsp, PPSSPP, and more.

My apologies about missing July’s roundup; I had a very busy month.

Nintendo 64 emulator Mupen64Plus has been updated to version 2.0. This release improves all the plugin modules, notably adding support for video window resizing and six new joysticks. It also fixes emulation issues with a number of games, including Donkey Kong 64 and Ocarina of Time. Check out the release notes here, then download via this page.

After two years without an update, Eric Shepherd aka SheppyWare’s Sweet16 Apple IIgs emulator has seen a major new release and a subsequent minor update. Version 3.0 drops support for PowerPC Macs, implements drag-and-drop support between the Mac and Apple IIgs Finder, adds a bunch of long-overdue features, fixes loads of issues, and improves everything else. Check out the release notes for both this and the 3.0.1 update at the Sweet16 website.

One year to the day after its previous release, Atari ST/STE/TT/Falcon emulator Hatari has been updated to version 1.7.0. This release adds an experimental MMU for the 68030 mode, improves accuracy in several areas, and makes a few other fixes. From a gaming perspective, 15 titles that previously had issues—including James Pond and Microprose Golf—should now work. The full release notes are included in the download (available here), while the quick-fire version is on the Hatari news page.

NekoLauncher Mednafen, a frontend/launcher for multi-system emulator Mednafen, has been updated to version 0.9.29. As has Mednafen itself, courtesy of idyll and Weedy Weed Smoker. For the uninitiated, Mednafen handles Game Boy Advance, Virtual Boy, Super Nintendo, and several other classic systems with aplomb, and it’s also an excellent choice for Mac folks looking to emulate PlayStation games. You can grab Mednafen with or without its frontend here, or pop over to Nekocan for just NekoLauncher Mednafen. And share your thoughts on the newly-minted MacScene forum thread.

Continue reading for more emulator news, including updates to Stella, Sheepshaver, and CocoaMSX, along with a couple of new additions to the scene.

There’s a new Nintendo 64 emulator on the block. I don’t know how Daedalus compares to Mupen64Plus or SixtyForce, as I couldn’t get it to run after compiling, but it looks to be under active development. You can grab the source from the Daedalus GitHub page. Let us know how it performs if you get it working.

ScummVM, an interpreter for dozens of classic point-and-click adventure games, has been updated to version 1.6.0. This release adds four new engines, which adds support for such titles as Eye of the Beholder and The Journeyman Project: Pegasus Prime. Other changes include improved support for Macintosh versions of a few games, an update to the Roland MT-32 emulation code, a grid chooser for save games, three new translations, and more. See the release notes for more details, and grab ScummVM from its downloads page.

Arcade emulator MAME reached version 0.149 a few days ago. As usual, this update includes a raft of fixes, additions, and tweaks. There’s a detailed change log if you want to see precisely what’s new. You can grab the source code from the MAMEdev site, or grab 32-bit or 64-bit Intel binaries from the SDLMAME site.

Almost-everything emulator MESS was also updated to version 0.149, with a similarly-exhaustive change log. You can grab its source code via either the MESS Wiki or MAMEdev site, and download binaries via the SDLMAME/SDLMESS site.

Mac gaming classic Pathways into Darkness, a precursor to Bungie's more famous first-person series Marathon and Halo, has been ported to OS X. This is a faithful, loving, free port with full blessings from Bungie. Go get it to revisit a slice of Mac gaming history. (If you're so inclined, I wrote up my thoughts on this OS X release here.)

There’s a new MSX emulator on the scene. CocoaMSX is based on blueMSX, and offers what looks to be a pretty robust feature set. You can follow its development on Google+ or track (and download) it on the CocoaMSX Google Code page. Be sure to let us know how it stacks up to openMSX (which has now moved from svn to Git repository, I might add).

Just over a year since the last release, Nintendo DS emulator DeSmuME has hit version 0.9.9. This build introduces a new JIT CPU core, which the devs say “yields some impressive speedups,” and specifically improves the OS X port with a ton of new options and enhancements. There’s also a bunch of bug fixes across the entire emulator. Get it from the official DeSmuME website.

Gaming-focused Amiga emulator FS-UAE has moved to fs-uae.net, and it’s been updated to version 2.2.2. Changes since March are mostly bugfixes and improvements to existing features. You can see lists here (2.2.1) and here (2.2.2). As always, head over to the FS-UAE website for more information and a download link.

Continue reading for more emulator updates, including new versions of two PSP emulators, long-overdue updates to ARAnyM and Bochs, and more.

Apologies for the break in service. We should be back to roundups every 4-5 weeks from here on out. We could always do with volunteers to help carry the weight, though.

Atari 2600 emulator Stella hit version 3.8 in February, with major changes to the sound system and ZIP archive handling. 3.8.1 followed at the beginning of March, with a few bugfixes and support for TIA RSYNC writes. See the Stella news page for more details. As always, you can get a download link here.

After taking more than nine years to reach its first stable release, ResidualVM has already popped out another one. Version 0.1.1 fixes around 20 bugs in the engine code and a dozen in Grim Fandango’s game data. Get it from the ResidualVM downloads page.

Sega Saturn emulator Yabause got its first update in 14 months near the end of January. Version 0.9.12 (link to announcement post) includes major updates to both the software and OpenGL renderers, adds ISO support to the OS X port, and adds the debug interface to the Qt port. Grab it from the Yabause download page.

Four years to the day after its last release, Sega Master System, Game Gear, SG-1000, ColecoVision, and NES (those last two are newly-added) emulator CrabEmu has been updated to version 0.2.0. You’ll have to download it for the full (and lengthy) changelog, but there’s been extensive work done on the GUI and Master System core.

Continue reading for more emulator updates from the past two months, including new versions of FS-UAE, XRoar, DBGL, VirtualBox (of course), and more.

Codeweavers released CrossOver 12 in mid-December. This version introduces an experimental new “Mac Driver” that removes the requirement for the X Window System (thereby making installation friendlier to casual users). CrossOver 12 also includes improvements to Wine and improved support for many applications. See here for the announcement post.

It’s been a long time coming, but ResidualVM finally has a stable release. ResidualVM is ScummVM’s sister project, focused on the handful of 3D LucasArts adventures—Grim Fandango and Escape From Monkey Island—plus Myst 3 Exile. This release supports Grim Fandango, making the game playable on modern computers. Head over to the ResidualVM website for a download and more information.

Nintendo Wii and Gamecube emulator Dolphin officially ticked over from 3.0 to 3.5 in December. This milestone rounds up work done over nearly 18 months, resulting in hundreds of nightly builds, and brings the “stable” codebase mostly up to date. You can get version 3.5 or the latest nightly builds from the Dolphin download page.
