So yesterday I welcomed a Japanese Gamecube in my console family. Its been hardmodded to play US/JAP games using a switch, and with the help of Freeloader also EU games can be played. Now, the Gamecube being Japanese, it uses NTSC, which is as we know operating at 60hz. My TV, being European and all, is PAL, so 50hz. Now I'm aware that just like that it doesn't work (or lead to the dreaded NTSC50). But my TV is also 60hz capable. So in theory, on a hardware level, it should work. Well it doesn't. I used the standard Gamecube Composite cables, both on the front TV inputs and via SCART adapter on both back slots. Result is a greyscale picture when attempting to play US games. And Mariokart Double Dashs Rainbow Road looks rather not rainbow-ish in grayscale. A solution to try would be hooking the Gamecube to the TV via S-Video (I have the proper cables). Now my TV doesn't have a native S-Video input, and I don't have an adapter. Would this one work? Or should I not even bother. If it wouldn't work, what other steps could one perform without actually getting a new TV? Note that I use a tube TV for all my old consoles. Also note that I'm aware of the fact that some Gamecube games have the option to select the Hertz value on boot, but some doesn't, and I want to play all games in color, not just some.
