Ok folks... this story is going to have an ending (hopefully a happy one). I made the short drive to whisper2053's place this afternoon. When we popped Genjin3 into his PC Engine Duo-R we got.... wait for it.... a white screen. Just like I got on my TE. It looks like, for as great as this card looks, its a dud. So I will have to try and get my money back. I would prefer a replacement if they have one. More to follow on that I guess.
While I was there I tried a few of his sizeable collection of JP Hucards in my TE and they all worked. Additionally, he had an Everdrive we threw in and it also worked perfectly. I might have to fork out the considerable cash for one of those.
I ended up spending a lot more time over there than I thought I would mostly just checking out all whisper2053's awesome stuff. I even learned a thing or two I didn't know.
Thanks again to whisper2053. He really came thru for me. If any of you deal with him in the future. I will vouch for him as a knowledgeable, honest, and very helpful dude that you can rely on.
