So last night I attempted the 60hz mod on my pal mega drive 2.
Unfortunately it wasn't totally successful. The mod has worked, the picture displayed is definitely 60hz, no borders and a slight speed increase, but whenever I push any button on the controller, the screen goes crazy. If I don't push any buttons, its stable.
To rule out my LCD TV, I hooked up the RGB lines to my Gonbes 8220 upscaler but that didn't make a difference either. I'm wondering if 60hz draws more current or something and my power supply is on its last legs.
Anyway I think I'll just end up buying an NTSC console.. unless anyone here as experience with this mod.
