No worries.
My only real question is why Chris didn't implement at least a single fire button and joystick axes input mapping. I had an 800 (with the 48k RAM expansion and 10k ROM pack) given to me by my 8th grade teacher so I could learn computers better, and I only needed the joystick with its single trigger (and very much cramp inducing design) and the 800's keyboard to play. But it's hard to play Star Raiders with no joystick. Ah well.
If the inability to enjoyably play Star Raiders is the worst of my "complaints", then I'd say I've got it relatively good in life, yes? So don't worry about it. I was at least able to play Sir Galahad and the Holy Grail again, complete with all the bugs and glitches when I ran it on the original hardware.
I'm curious why Apple hasn't included the latest C++ extensions in XCode though. It seemed for a while once XCode came around and we were able to ditch CodeWarrior, that we (Apple/OS X) was racing ahead, perhaps not as far ahead as the general Linux distros' compilers, but better than what Windows had. Yet now it seems like we're falling further and further behind. Apple seems focused on forcing iOS on all of us (Lion's internal unkillable features) and stiffling any real advancement by anybody other than themselves on OS X. Being such that it is, I can wholeheartedly understand and agree with how you're handling things - it's hard to make advances when there's brick wall after brick wall in front of you, so you're left with basically putting out maintenance updates for as long as the API you use is supported. I used to be "gimme gimme gimme" and "it's broke FIX IT", but these last few years have taught me a fair bit about why you and others like you can't just revamp things willy nilly - it just ain't that easy.
Anyway, one game is hardly anything worth losing any sleep over. I have tons of other options via your other emulators, and I can still play the 2600 version of Star Raiders (which is the original version I grew up on anyway), so go enjoy yourself. And be proud that your software is among the tiny tiny percentage of software out there that has survived three major OS releases without any real need for change. If it ain't broke, why fix it?
(Sure wish Blizzard would learn that one...)
P.S. - My only regret with Atari emulation is that I know of no way to "fry" a 2600 via emulation. Doing so introduced some hilarious effects into games.
