I just spent a few hours with my newly arrived 2600+. Overall, it does what I want it to do, which is to eliminate signal drop on my 4K TV that I get when using original hardware for certain 2600 games - even with a RetroTink 2xPro. I know that the Retrink5x and the RetroTink4K can handle this, but I am not sure I want to invest the additional $300-700 for a handful of 2600 games. None of my other legacy systems have this particular issue through my current set-up.
Here are some quick pluses and minuses:
+ I find the output to be cleaner than either a Retron77 or my modded hardware through an upscaler.
+ it records perfectly with my AverMedia Live Gamer 2 Plus.
+ Load times using the hot swap are minimal
+ No noticeable lag, despite some reports to the contrary
+ Nice build quality on the console, joysticks and (in particular) the new Paddles
+ It plays all of my "go to" 2600/7800 retail games without issue
+ Worked with my third-party controllers and legacy Atari controllers
+ Works with XP games
- Does not currently play 7800 homebrews and hacks. Although this is likely to be addressed in a future firmware update, I have a lot of 7800 homebrew.
- Does not load my copies of 7800 Rampage or Double Dragon.
- Difficulty switches are backwards
- No support for keypad controllers
- No support for the driving controller
- No scanline filters or save states; I think some modern creature comforts should have been implemented. If you're going to do it, do it.
Other thoughts:
I only have one Melody board homebrew and about 20 ways to play it, so I'm not overly concerned that the 2600+ doesn't work with these. 2600 homebrew that isn't chip assisted works fine.
I'm looking forward to seeing how Plaion/Atari respond to early feedback and I'm hopeful that the promised firmware update addresses 7800 homebrew and specialty controller compatability. For now, this is better than the Retron77 but doesn't quite replace original hardware. It looks like I'll be leaving an original 7800 in the mix for the time being.
