Are there any AV to HDMI adapters that work for the N64? I recently dug out my old N64 and Dreamcast and then ordered a little $10 MINI adapter online so I could hook them up to my modern tv. It works fine when I put my Dreamcast in but when I put the N64 in the picture skips like crazy. I have an audio cable hooked up before the adapter (my tv is a monitor with no sound) and the sound is fine so I'm thinking the adapter doesn't like N64 signal for some reason. I've heard that these things are really finicky and sometimes work but sometimes don't. Are there any good ones out there that do work for this system?
