Metroid Zero Mission looks gorgeous on CRT in 240p or 480i (mGBA Wii emulator), but the 30hz flickering spotlights are painful to look at.

For the longest time I'd get random signal dropouts every few hours. Observing the GBS-C's output VGA line revealed horizontal sync frequency excursions, and observing the input luma+SoG line revealed high-amplitude noise bursts at 8 MHz or so. After months of debugging and ordering a multi-hundred-dollar oscilloscope, I discovered a malfunctioning light dimmer switch in my wall was likely generating RF interference, causing my Wii to output a garbled video signal to whatever load was present (eg. GBS-C or a 75 ohm RCA terminator). My debugging log is at https://github.com/ramapcsx2/gbs-control/issues/461.

For me, the flicker looks fine in games... and less fine in primarily-white screens like game loading screens or computer desktops. I've read conflicting information over whether TVs had longer persistence than monitors.

Miniature Wii sensor bar. I ended up moving it below the monitor, since you hold your Wiimotes below eye level, and the Wiimotes weren't built for being held so close to the monitor (so keeping the monitor at eye level and Wiimote at arm level would position the sensor bar out of the camera's field of view). The cable now gets in the way of the front-panel controls, but it's the price you pay for playing Wii games on a 17" VGA.
