Sorry bout the lack of comunication

Good news, been making a lot of progress, I just keep wanting to add more and clean things up before I release a preview version. And this "real life" thing keeps getting in the way.
List of stuff I have working reasonably well...
Video with the built in filters (started playing with CoreImage filters as well [see MAME OSX for an example of those])
NES Pad, Zapper, Mouse, Arknoid control and Barcode reader for input
Save/Load state
Battery backed save/load
Stuff in progress:
Sound...CoreAudio is a complete PITA...
Preferences, trying to expose everything through the GUI while following the Aqua L&F
Stuff im looking at:
Gamepad support, using DDHidLib
Anything else people would like to see? Or is a low priority for them? My lack of sound is one of the main reasons I havn't released anythign, that and the fact my code keeps getting refactored. I keep learning more about Obj-C as I go and change things.
Also:
Realized I have no clue if this will run properly on a PPC mac. If someone wants to be my guinea pig, let me know. Either that, or someone can send me a PPC mac :P
