I read some of the recent interviews from GoG founders that were recently linked on the main page. They said that part of why they were offering DRM free software is because they saw pirates as being one of their main competitors. They see themselves as providing a better service than the pirates.
This got me thinking-- one of the main ways that people pirate games online is through emulators and roms. I wonder if it would be possible for gog to ever partner with nintendo, sega, snk, etc. to release legal digital products that could compete with emulation piracy?
For any gog staff paying attention, have you ever considered partnering with the old console giants to release virtual consoles and games for PC?
For everyone else, would you ever buy from that kind of service. What sort of extra features, bonuses, and support would make that kind of service something you would want to pay for instead of just taking the easily available emulators and roms that are already out there?

this has been discussed before, I do not readily have a link though.
I believe we agreed it shouldn't happen.

Sega, possibly (they've put some of their Genesis games on GameTap, haven't they?). The others, I'd say unlikely.

Sega and SNK? Yes
Sega and SNK loves to reintroduce their generation of awesomeness to as many people as they can. Capcom could be included into this aswell since every numbered Resident Evil has been ported to PC.
Nintendo? Hell no
Nintendo prides itself on repackaging and reselling the same damn games every new generation on their own proprietary consoles.

It's been well talked about as Weclock mentioned. Legal emulation is a bit of a nightmare. Some companies are up for it and others not. Sega already emulates a lot of their classic Genesis games on both Xbox Live and Wii and I know they have websites that also allow you to play them. The problem is would Sega allow GOG to licence the important Bios of consoles like the Saturn or Dreamcast. zSNES works very well but it will be a cold day in hell when Nintendo allow it legally on PC.
The best chance of an Emulator would be the Commodore Amiga as GOG already have deals with publishers who made games on that format. Then again they would need to licence the Kickstart ROMS from Amiga Inc or Gateway.

Console brands tend to be a lot more uptight about such things, recycling games over and over as long as they can - especially Nintendo!
You only need to look at the Wii store to see this. Charging $13 for an average 20 year old NES game is ridiculous. At least on GOG you get quality games at half that price with manual and other extras.

Legal emulation on of the 8/16bit era is something I would like to see, but perhaps not specifically here at GOG if draws attention away from PC classics.
ROM Piracy* is fairly high on the PC from what I've seen, someone needs to capitalise on the demand :)

I'd love to see someone try with Amiga what GOG has done for DOS. WinUAE is a lot harder to use though, and takes quite a bit of knowledge to know how Amiga games work.

Harder? I don't remember ever having problems with WinUAE

SEGA will never happen, at least not on GOG for the simple reason that they will never get world wide distribution. Sadly, you'll never get SEGA Japan agreeing to it. For that matter all other relevant Japanese companies will be the same.
The Amiga too, probably won't happen as Cloanto now own the relevant architecture/bios roms -- I could imagine they'd want to charge GOG far too much in order to license the roms.

Maybe you owned an Amiga in the past then? Or you put in enough time as well? No WAY a casual gamer will be able to work with it.
Let's see:
You need half a dozen different ROM files to start with.
Quite a few games need a special savegame disk which means you need to know how to correctly format and name such a disk.
You got disk loading speed which can't be set too high but if you set them low, it can take ages for a game to load.
Some games need a hard drive, others run off the disk.
Some games only work on the A500, others need the A1200.
etc. etc.
WinUae has hundreds of settings after all.
As a non-Amiga user it took me many hours to figure everything out on my own. I could have used Quickstart, of course, but I didn't because that doesn't work with all games. The different Amiga releases are what complicate matters so much. Trust me, the huge bulk of gamers who never had an Amiga wouldn't be able to understand it. Heck, I'm also on the DOSBox forums helping out people and many have trouble typing in "dir" and "cd" so this is way beyond them.

Same here but to open a store and expect everyone to be like that would be commercial suicide. DOS is not that hard if you stick to the basics yet it's already too hard for many users. They need to type and they panick!

Red Avatar:
Many of the games on gog already require stuff thats way above casual users, locking threads to a specific processor and running tools that max out CPUs so no frequency-changes occur.
And dont even start talking about games that use Dosbox.
Messing with WinUAE shouldn't be a concern as similar to the games already on gog they could simply come with an preconfigured Emulator and place a link on your Desktop.

Yeah about the only issue beyond the licencing is the makeup of the interface. Would you have to buy a virtual amiga to use the discs on or would they all be self contained?
The virtual amiga might be more fiddly but you'd only have to pay for the kickstart image once rather than with every game
