DeSmuME is the best Nintendo DS Emulator for Mac OS X that I have found, it’s pretty full featured with save states, touchscreen emulation, movie creation, and more. My only complaint is the layout of the emulator being vertical, which is true to the DS, but it makes playing games sort of obnoxious particularly when you increase the screen size. If they enabled side-by-side screens for this DS emulator so I could play it fullscreen, I’d be even more enthralled with an already good app. If you’re looking for a Nintendo DS Emulator for your Mac, look no further.

Looking for a PS2 Emulator for Mac OS X? Look no further then PCSX2, a full blown PS2 emulator for Mac OS X that works surprisingly well. I say surprising because it seems development work is a little infrequent and there are some features left to be desired, but it certainly works and the frame rate is pretty high on my MacBook. Finally, I can play all my favorite PS2 RPG’s right in Mac OS X!

Carrying around a stack of CD’s and DVD’s just so you can play games can be very annoying, adding unwanted bulk to your pack. Well, I came across this tip today and I think it’s particularly useful for Mac gamers who own laptops, but it’s just as useful for desktop gamers. Macinstruct wrote up an easy to follow guide on how you can play games on your Mac without the CD/DVD by making an image of the disc with either Disk Utility or Toast. It’s pretty self explanatory but if you’d like some assistance setting this up be sure to check out their tutorial.
