Emulation and licenses aren't cheap, so I'm afraid that holds a lot of these dreams back. But AtGames is committed to delving deeper into Atari's legacy at least, so some of this should be coming to fruition from 2017 onward.
For an example of the issues, here's where the Lynx library stands today per AtGames (That post comes from their representative/adviser that posts at AtariAge). http://atariage.com/forums/topic/254611 ... try3589922
So there's a grand total of two games that are available for AtGames to use that Atari's corporate legacy today owns, but which also doesn't utilize an outside license of sorts. Obviously between the small pool of readily available software, the complexity to emulate the platform, the cost of outside licensing, and its failure in the marketplace, we can safely count on never seeing Lynx games in a future Atari compilation.
Heck, even look at the 7800 library. I don't know the legal status of this software, but when you scrap the license based software like Ms. Pac-Man and the light gun shooters that lack a joystick mode from Atari's in-house lineup, you're left with approximately this list of likely candidates.
Pretty slim pickings, not to mention that the three best games have all been emulated in arcade form in the past 10 years (While sadly absent on these latest collections, Food Fight reappeared on the 360's short lived Game Room service) and two of them also have 2600 ports that have regularly seen the light of day. And we don't know the legal status of these titles either, which could be problematic such as with the GCC developed arcade ports.
So I'd say that we can't even count on 7800 emulation ever happening commercially (Or Jaguar and ST emulation).
