Hanglyman: I'm curious, was there a difference between the Mac Collector's CD-ROM and the PC one? I recall playing a version of TIE Fighter that had iMuse, voiceovers, clean and clear but not 1998-version-reskinned graphics, and the newer transition and concourse graphics. However, that was on a Mac. The PC version seems to have everything except the newer transition and concourse graphics- the gameplay, music, voices and mission cutscenes are all exactly like I remembered them, but I remember the combat chamber, registration, etc. as being the 1998 graphics. Am I just remembering wrong?
Either way, I'm overjoyed to have iMuse back and at the same time not have everything be a blurry clump of pixels with no voiceovers. The gameplay is finally perfect, and that's what's most important.
I grew up playing X-Wing and TIE Fighter on the Mac as well. I had the Macintosh collector's CD-ROM versions of both, and recently bought the GOG versions to get my nostalgia on.
They are great, except they aren't exactly the same. I've done a lot of research trying to set everything up just right, but it appears that the old Macintosh CD-ROM versions were "unicorns" so to speak - they are the perfect versions, with 640x480 graphics throughout (both menus AND flying), prettier concourse graphics and cutscenes, while maintaining the iMUSE dynamic music, mission briefing music, concourse music, etc. They also added a "match speed" button. I think they actually ported X-Wing to the TIE Fighter engine. The 1998 versions are ports of X-Wing and TIE Fighter to the X-Wing Vs. TIE Fighter engine, which doesn't have iMUSE.
As far as I can tell, there was never a Windows equivalent to them. So for X-Wing, you must choose between iMUSE or 640x480 flight resolution. TIE Fighter is a little better since at least the flight resolution is 640x480, but the menus are more pixelated.
The only other option is to buy an old Mac, a joystick, and find a physical disc copy of those games. Could be expensive.
