Keep in mind that if you install Borti’s bypass board in a PAL console then you need to buy a NTSC RGB cable. If you buy a NTSC CSYNC cable and accidentally plug the cable in an unmodded PAL console then it will output 12volt instead of CSYNC. That might damage the device you connect it to.
I recommend you just buy a PAL luma sync cable and if needed do the simple brightness mod if you buy a 1-CHIP console.
Another option is the HDRetrovision component cable that works with PAL and NTSC consoles and have a brightness switch for too bright 1-CHIP consoles.
