I think I killed my DUO-RX when RGB modding

all the PCE/turbografx chips are interchangeable between systems

The problem is you tried to lift 1 leg at a time!  The correct solution now is to use a hot air reflow station to remove the entire IC.  Clean the board, see whats broken and test the IC.  Then, if the IC is good, solder it down and repair.

If legs are broken / missing, get a new IC from a donor board and transfer it over.  This is very common repair process with arcade PCB's, just now applied to a Duo.

except in this case we have the schematic and know most of the pins lifted didnt have traces, and the ones that are visible except 1

Fantastic, just the kind of thing I need!  Thanks!

I feel bad about having to sacrifice a Core Grafx system, but I'd rather have my RX back over a system I will never use.

Sega,

Don't feel so bad; my first Turbo Repair back in 2008 was terrible; I ripped up a bunch of the traces and nearly destroyed a Turbo Express... but I posted about it here like you did with this Duo, and Steve and chop5 walked me through the repairs and helped me get the unit running again. It looks like Frankenstein inside, but I still have it and play it frequently. 

Getting your Duo going sounds possible. Good luck, and keep us posted.

Isn't the 6260 inside the Ten no Koe as well? Unless prices have shifted since I last looked, I think those are cheaper than a Core Grafx.

In closing, I just wanted to say, don't let this experience turn you off from wanting to do mods / repairs. I'm sure everyone has some stories to tell. I finally had my first big fail and killed a Super Famicom. Once you get the hang of it, the feeling of knowing you can do it yourself is really rewarding. So hang in there.

dont see why the ten no koe would have a video processor

I know they have a watch battery inside them. I recall an ancient "repair" thread:

I should have been clearer. I am talking about the Ten no Koe 2, the thing that clips on the back of the Core Grafx. I remember when I cracked mine open to put an RGB amp in it, there was a chip that looked like the 6260 sitting on the board inside it. I just can't remember what chip it was.

Ahh, well then I have no idea, because I have never owned a TK2.

Why not buy a junky white PCE from Japan?

That probably was the save ram chip

edit:
its HuC6201.  not exactly sure what its for.

Used 6201 which is like a CPLD to handle bankswitching between the host console and the 2k SRAM chip. Not video chip for sure.

The video chip only exists in consoles so  dig up those junky PC Engine or Coregrafx for the parts.

Thank you to everyone for the kind and encouraging words    I will keep modding stuff and I really think that I learnt many lessons through this horrible mess.  Just wish it didn't take the "death" of a DUO-RX to give me the experience.  I intend to grab a NESRGB from Tim once I have some spare money, hopefully soon.  With all the games coming out in Japan in Jan/Feb, spare cash will be sparse.  Desoldering the PPU should be a nice "fun" challenge for me to do.  I have 3 or 4 junky Famicoms that I have no use for, so I may practice on one of those first.  Still have not decided if I want to do one of my Twins (I have 5) or my AV Famicom with FDS system.

I have the DUO RGB wires soldered to the 6260 chip, and I did it with not a single problem.  Have yet to put the DIN8 in, yet, but will do it when I finish off the caps tomorrow.  The IFU has all the wires soldered but not yet hooked up to the amp or DIN8.

I do not have a 15mm drill bit, nor do I have a dremel so I am trying to work out the best way to drill/make the hole in the IFU case for the DIN8 to be installed.  The psu's I ordered should be here on Monday, I hope. 

The place I ordered it from sent an email on the 30 December saying the items had been sent, but did not give me a tracking number.  I emailed and asked about it a few days later and when they replied, the tracking was showing that it had been sent on 5 Jan.  It makes me think that they forgot to send it and only did so once I emailed them.  They should have been here already.  I know they are in the country, but I do not know WHERE in the country they are.  EMS from Japan always annoyingly goes to Sydney.  I am hoping this French package has come to Brisbane directly.  I want to make sure the systems are ready to be tested as soon as the psus arrive.
