I have an oem snes s-video cable for my ntsc-u GC and launch snes. Not so long ago I grabbed a snes mini modded for rgb and have proper scart cables/adaptors for use with an old pvm monitor with csync.MechaGodzilla wrote: Retro/hoarder types - the fairly cheap S-video cable you can get off amazon (I think mine was about £15?) makes a noticeable difference on my PAL GameCube, presumably SNES and N64 too. It's not progressive scan but it's an improvement on my fairly up-to-date-but-budget LED TV.
PAL gamecube has native RGB output capability. You can use nintendo-to-rgb or nintendo-to-scart to scart-to-component etc with an rgb monitor, no modding required.
If you want zero input lag and the least frustrating gaming experience, it's worth it (providing you've got some budget to invest in a rig you plan to keep).
However...there's nothing inherently wrong with having a super simple composite+crt setup. It's how most of us played in the 90s, before that it was with coaxial connections. Your local thriftshop can provide a score for about $30. In any event have fun
