Thanks a lot Frankie!!! I have been curious about this clone for some time and didn't know if the rumors were true about it playing Castlevania III. I'm happy to see that it does.
I almost bought an FC Twin a whileback. Thankfully the place I went to buy it had had one on display. While the SNES looked and sounded good the NES sounded terrible. They had the first Super Mario Bros. setup to play and the music sounded completely different.
So I wanted to ask... When playing SMB 1 is the NES sound on the Retro Duo better than the NES sound on the FC Twin? If so... then that seals the deal and i'm buying one.
All in all that was an excellent review. Answered everything els I needed to know.
