PlayStation Portable emulator PPSSPP has been updated to version 0.9.9.1. This fixes a few issues discovered in the 0.9.9 release, which added support for the mp3 and aac codecs and PMP video format, fixed a number of graphical issues by adding CLUT/paletted texturing from framebuffers, improved vrot CPU instruction emulation, and much more. Mac builds are still not officially supported, and the angelXwind site that normally hosts unofficial builds seems to be down, but PPSSPP forum-goer slavezeo put together a script that can be used to compile the emulator with only a little modification.

Nintendo Wii and Gamecube emulator Dolphin apparently received hundreds of code optimisations in July, resulting in big performance improvements, fixes to long-standing bugs, and even a few new features. Read the typically-fascinating Progress Report for a rundown of the most notable changes. They've also got a review up on the Dolphin blog for the Mayflash DolphinBar, which is a USB sensor bar designed to work with Dolphin and as a mouse replacement. If you're after new builds, there's a steady flow of automated development versions appearing every day.

It's been a long time coming, but ScummVM 1.7.0 was released in July. Five new games are supported, including 1996 claymation The Neverhood. Changes include "many" improvements to the UI, an OpenGL backend and enhanced AGOS engine, and updated MT-32 emulation. You can read a full breakdown of the changes in the release notes. Get it from the ScummVM download page.

Emulicious, a Game Boy, Game Boy Color, Sega Master System, and Sega Game Gear emulator written in Java 1.6, is now available. The current version has built-in IPS patching, palette and tilemap viewers, a memory tracer, a debugger, and more. The developer also built an Alex Kidd in Miracle World editor, which looks pretty handy for would-be ROM hackers.

Atari 2600 VCS emulator Stella has a major update available. The 4.0 release ports Stella to SDL2, allowing native hardware acceleration. Other changes and additions include preliminary support for the DASH bankswitching scheme, a hidecursor command-line option, an updated PNG library, and more. Head over to Stella's news page for the full list.

GSport, an Apple IIgs emulator, has been updated to version 0.31. This build introduces AppleTalk networking emulation with bridging to EtherTalk (online multiplayer!), allows pasting of (text) clipboard contents from OS X, and fixes a few bugs, among other things. You can see the full breakdown here.

Sixtyforce lives! After many years of development and a trickle of releases, Gerrit Goossen's Nintendo 64 emulator has hit the big 1.0 milestone. Additions include improved controller configuration and support, a new timing mode, new low-level graphics processing, and more, while there are also a bunch of bugfixes. See the release notes for full details. And remember to pay for a licence if you'd like to see better Nintendo 64 emulation on the Mac.

Nintendo Wii and Gamecube emulator Dolphin has shed its 32-bit support — although that shouldn't have much of an impact on us Mac users. Development highlights from May include a wide-reaching fix for indirect texture coordinate computation, fixed external frame buffer width/height handling, improved DVD seek timing, and a change to frsqrte and fres calculations (they were too precise) that fixes scores of problems. The latest dev build at the time of writing is 4.0-1859, with the most recent stable release dating back to 4.0.2 from the start of the year.

Macintosh II A/UX emulator Shoebill has been updated to version 0.0.3. This release adds support for PRAM and full-screen mode, plus you can now restart/shutdown the virtual machine without it crashing, and Shoebill uses less CPU when A/UX's scheduler idles. Get it from the Shoebill GitHub page, and follow the discussion on E-Maculation.

Game Boy emulator DMGBoy got a major update in May. Version 2.0 adds Game Boy Color compatibility and a GUI debugger, as well as a nifty 3D model of the original Game Boy that you can play your games on (see video below). You can also now resize the window in real time, with no change in aspect ratio. On my Mac it was throwing up wxWidgets errors on run, but it seems to work just fine if you suppress these. Get it from the DMGBoy Google Code page.

Continue reading for more a series of minor emulator updates, including new Mednafen, Bizhawk, and Bochs builds.

(I had this one half-done three weeks ago, and only just now got a chance to wrap it up. Hopefully we'll be back to a monthly schedule on these from here on out.)

Arcade emulator MAME has been updated to version 0.153. This release brings big changes under the hood, with major revisions made to modernise the core, user interface, OSD layers, drivers, and devices. Be sure to read through the What’s New document for a detailed rundown if you’re at all interested in the project and/or its goals. As always, you can get more general information and source code from the MAMEDev website, and there’s a Mac-specific binary on the SDLMAME site.

Multiple system emulator MESS has also been bumped up to version 0.153, with the most notable additions being support for 1979 console Bandai Super Vision 8000, the UK Apple IIe models, Serbian computer Pecom 32, and two systems I’ve never heard of: the Samsung Gam*Boy I and AIWA MegaCD CSD-GIM. See here for the full list of changes, and here for 32-bit and 64-bit SDLMESS binaries.

Macintosh II A/UX emulator Shoebill is making great progress. Developer Peter Rutenbar is reporting that A/UX 3.0.0 now runs, although there are still some issues. 0.0.2 boasts modest speed improvements and bug fixes, and it removes the need to supply your own kernel. You can download it or grab the latest source code at GitHub. Keep an eye on the E-Maculation Shoebill thread if you're interested in the project. Next up will be A/UX 3.0.1 support (maybe).

Recommended reading this month comes in the form of an article on the challenges of pixel-perfect Gamecube and Wii emulation, with specific examples of how Dolphin has tackled these in the past and present.

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.

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.
