I'm interested now
Its me again....I got another set of the Retro Duo today(Black model)...I did some comparison side by side between the 2 models(White/Black),and found just a few differences.It seems to be more than one revision made to the Retro Duo mother board.The only change that I noticed between them was just a chip...For some reason the controllers included with the white model are better responding than the ones found with the Black one,specially with fighting games such as Street Fighter II where you have to make all sorts of moves...The white system cartridge ports seem to hold in place the games better.The cartrige ports found in the Black model are a bit more loose when inserting a game...the s-video signals provided by the white model are just a notch cleaner than the black one,but the sound is much better within the black system.They both have the same Samsung RGB encoder!...If you are curious to see what the Retro Duo motherboard looks like,take a look!...

There is a clock missing in both of the boards but I'm thinking that it may be for the PAL systems.

GREAT info!
Admittedly a bit of it is greek to me, but I understand the concept of A/V output mods.
Keep us posted if you attempt an RGB mod.
"And the book says: 'We may be through with the past, but the past ain't through with us.'"
huh... that's really weird! thanks for this tid-bit! i only have a white one so i wouldn't know there was a difference. of course, i bought my brother a black one, but he hasn't even opened it yet.
If you are able to compare the 2 models whenever you get the chance,let us know if you find any differences...Believe it or not the cartridge connectors for the SNES and NES sides on the white model are better quality than the ones within the black.
For those wanting to get RGB..The RGB lines can be easily driven out with a 75ohm resistor and a 220uf capacitor for each output line from leg 21,leg 22 and leg 23 of the Samsung KA2198BD.There are plenty of data sheets for this particular encoder out there...Since the Retro Duo directly uses the s-video output lines from the encoder,leg 15 and leg 16 (C/Y) ,it would be wise to disconnect them from it,otherwise it may become corrupted and there will be no RGB mod for anybody!
Hey GAC, where are your repros from you tested? I got an Earthbound Zero from Dave that he made, and I'm looking into gettting a "blinkless" NES device to play it on...
How do the PAL games work on this, anyway? No rolling screens?

We did some testing (on video for posterity) of a bunch of games at the NAVA meeting, I need to cut the videos together to fit on one or two YouTube spots, but here's the rundown of what we found :
Gauntlet for NES (the black unlicensed Tengen version) works fine. MYTH BUSTED!
Rolling Thunder for NES (also black, unlicensed Tengen version) does not boot on the Duo.
A TON of other strange unlicensed stuff and random NES cartridges worked GREAT, including but not limited to : Quattro Adventure, Chiller, Sunday Funday, Bible Adventures, Star Tropics 1 & 2, Pacmania, Klax, The Adventures of Bayou Billy, Batman

I can't wait to buy one, I just need to find out if MegaMan X2 or X3 works on it. Impressive that Stunt Race FX works however
These cartridges are dirty as hell and I'm not going to take it anymore!
I got mine from Dave as well, it should work.

Good to hear!
So where's the best place to score one of these? Maybe some of the shops in madison would have some, hmm.
i'll do that when i get the chance. my brother wants to finish his ps game of chrono trigger before he busts out his retro duo. then he says he's gonna play secret of evermore and super mario rpg. so i'll see if i can tell any differences!
I got to see one of these first hand today. They look pretty nice, but the dpads on the included controllers are dreadful.
You are totally right!....those D-pads are not very responsive...But it is only a D-pad plastic molding flop,nothing mayor....I had a dead original SNES controller and did some D-pad swapping between them two and now is all good....
