Yes, I'm aware of that, but the PC has nuances, too. You can't just write a
simple x86 emulator for Wine and expect it to work seamlessly. It won't. I
was just trying to make a simple analogy. UltraHLE is substantially more
complex than a simple emulator, and implementing good x86 support in wine
would take substantial time from a talented developer who could otherwise
improve it in more important aspects (such as running more applications).
You have to face the facts that Macs have a small market share, are
relatively expensive, and that few people want to use them to run the same
old buggy apps that they used on Windows. Most of them don't run under wine
The main focus for wine right now is implementing the API and making a
substantial amount of the major Windows programs work flawlessly. Most of
them already run on the Mac. Most people who have a Mac and want windows can
afford a copy of VirtualPC. This is simply an issue of priorities.
