The most use I've got out of the Nintendo Wii is Virtual Console titles. It is a convenient little emulation box allowing purchase of downloadable retro games for various Sega and Nintendo consoles, as well as the more obscure consoles like the NeoGeo and TurboGrafx.
Most Wii VC games run at the original native resolution of their cartridge counterparts: 240p in NTSC regions and 288p in PAL regions. Most modern televisions do not support these resolutions through component or HDMI, so many of the games have a "Component AV Interlace Mode" to convert the games to 480i/p or 576i.
F-Zero for the Super Nintendo seems to be a bit of an odd ball. I don't have an NTSC Wii to test, but the PAL version of the F-Zero VC download ONLY outputs at 576i - even with the interlace mode switched off. And it seems to be a 240p to 576i conversion, rather than a 288p to 576i conversion. Subsequently, the game suffers from horrendous combing.
Trying to get good quality out of F-zero has proven extremely difficult. For comparison purposes, here's are various capture tests using different Wii HDMI adapters and even RGB SCART vs the native 720p version available on the Super Nintendo Classic Edition.
