You guys ever hear of the "VGA666"? Well, I bought a SCART666; a custom-made adapter for Raspberry Pi, based on the original VGA version. It even uses the same config. It arrives tomorrow, but promises easy 240p gaming, and all it uses is the GPIO port of the Pi. I'm not european, so I don't actually have a CRT with a SCART port, but I do have a SCART-to-Component adapter I used with CRTEmudriver, so I'll try my luck with that.
