Ok I own a Mint Complete US TurboDuo system and have thought about trading for a Duo R/RX system. I have not ran into any problems with my system like what is been known to happen (The sound issue where it starts sounding bad after playing for a while). The only thing i notice is that some games consistantly have slight humming/hang in the sound when the volume is way up, which i am sure it is normal since my US TG-16 still does that on the same hucards.
Are some people lucky and get a better made Duo or are they all going to do this happen some day?
Did you buy your Duo brand new? I think that how people threat their systems have a lot to do with the problems their Duo's may or may not develop.
I still have the Turbo Duo I bought within a few months of its release and it plays all games, including cdrs fine.
I have a nearmint/mint Duo RX and although it works well enough with original games, it sucks with cdrs.
The Turbo CD I bought and used regularly for 10 years before accidently losing it never gave me any problems either. But the RF out on my original TG-16 screwed up(probably because of the huge plug) and I had to get it refurbished by NEC(they took in only the console, but shipped back a complete package with accessories & Keith Courage).
I'm still pretty rough with all my consoles(I tore out the AC in of my Duo and had to patch the back side after a botched repair job) but one thing that stands apart from some other gamers is that I can't handle cigarette smoke and don't let anyone smoke anything anywhere near anywhere I live.
If I were you, I'd hang onto your Turbo Duo and if you really want an R/RX, just put some cash aside for one since they go for half as much as a Turbo. If you want to prevent a potential problem from over heating, I suggest getting a fan installed by D-Lite.
