Not having the best of luck over here again! Just got another Duo, this time an R, from yamatoku-classic, and this one (even though listed as tested) has issues too. Hu-card games seem to run fine, but the CD portion doesn't seem to work at all. When I try to load a cd game, it blinks and flickers, makes a weird sound out of the speakers, and eventually says load error.
Here is a video of what it's doing: http://youtu.be/wtcq-7oB4Lk
This is probably just a cap issue, right?
Thanks!
Nevermind!
I was using an aftermarket genesis 2 power adapter I bought off Amazon. It appears that it didn't produce enough power or something, cause when I used my real genny 2 power adapter, now it works. That being said, there are some weird graphical and sound glitches now, but I think that warrants a new/different post.
