lxdream, the Sega Dreamcast emulator for Linux, was ported to x86-64 and Mac OS X.

From the official page:

It must be porting week - both the x86-64 and mac ports should (fingers crossed) work out of the box now. (Note that the mac port is intel only, and still requires X11+GTK 2.0 to build). Real native mac support will probably follow slowly as time permits - I’m getting something of a crash course in mac programming at the moment .

 

Changes

 

* Added x86-64 support to the translator

* Initial Mac OS X support (configuration and translator ABI changes)

* Fix buggy TRAPA instruction (translator only - fixes several homebrew games)

* Improve error handling of a few situations (can’t connect to display, etc)

* Esound is now optional (but without it you’re not getting any audio)

* Re-add the “Load Binary” menu entry that somehow got lost in the GUI revamp.

TG16 / PCE emulator

2007/11/22 1.28 released

- The resolution of "PSG-sound(wave memory sound)" improved. As a result, the tone has approached a real machine. Especially, I think that it can feel it remarkably at "Galaga'90(Galaga'88)" and "Atomic Robokid Special", etc.

- The capacity of default of the sound buffer was reduced. As a result, "Timing that the sound rings" has approached a real machine.

- Processing that plays CD sound source (CD-DA) has been improved. At the sound test of "Akumajou Dracula X", When the tune was selected, the problem that had stopped occasionally was solved.

- In "Order of the Griffon", "Ryuuko no Ken" and "Asuka120%", the image quality has been improved (The burr is cut). And, the processing part was sped up.

- In "Downtown Nekketsu Monogatari", the problem that the start screen shook was solved.

- In "Lodoss Tou Senki II", at the scene of "House of Parn", etc. the problem that the screen has fallen into disorder was solved.

- Additionally, a detailed part has been improved and corrected.
