Dolphin bar is kind of slow/laggy. Other M is frustrating enough without piling laggy controls on top. I haven't gotten the right adapter to try that bluetooth passthrough mode but outside of that, motion controls are bad enough that I'd rather deal with that ugly-ass OG hardware. If you can find a widescreen CRT or one of the many WEGAs that offers a 16:9 mode that is kind of ideal.
There's some minor glitch in early Wii models that slightly degrades 480p output, be sure you are using a loader with the fixes applied.
