I have a question too! Two, in fact! I may actually cross-post some of this on the official Dolphin forums, but I figure someone here might know too.
First, I'm interested in permanently associating a Wii Remote with one of my bluetooth dongles. The goal is to hide Windows behind GameEx as completely as possible for everyday use, and for the interface to be completely gamepad-controllable. I have no problem actually associating a Wii Remote via Windows's bluetooth setup and with Dolphin's "Pair Remote" functionality, but both require me to break out of the GameEx interface and start mucking around with emulator settings. Does anyone have any experience permanently pairing up a Wii Remote with a PC, so that just by pressing a button on the remote it turns on and connects (just like it does with a regular Wii?) I found http://forums.dolphin-emulator.com/showthread.php?tid=22165
this thread and I intend to try it, but I don't know what the difference is with this "Toshiba bluetooth stack" or how to install it on my Targus devices or anything along those lines.
Second, Sliver-X (who built all the guts that run in the background, and there are a _lot_ of guts) has informed me that I need a custom file extension for basically every system that's being loaded. ISO is currently reserved for SegaCD, though I may end up tweaking that a bit. The issue is that if I change the file extensions on my Wii stuff (say, to .wiso or to .wii) Dolphin no longer recognizes them. Is there an easy way to get Dolphin to recognize them?
