Homebrew compatibility?

No.  That's a no for some retail era games too.   On a cellphone so it's hard to type.  I'm sure someone will point you to Ataris tested/untested list.

 

This is an emulator in a box.  Expect at least the basic advantages and disadvantages of a Retron 77 without community firmware.

That's what I heard but wanted to confirm. Well, that's another Atari product I'm not purchasing, rather just get a third 2600 from ebay. Though for collectors' sake, I might pick one up second hand in the distant future.

 

A note to Atari: IF you are going to do something like this, put an actual 6502 chip in the box, better yet, an FPGA...it's cheap, not difficult, and you can have it work with everything. Anyway, keep trying though!

Yep, and once you buy that 2600 and then HDMI mod it so you can use it on a modern TV, you have a great system...

That is awesome...

 

Some people just want something simple to plug in and work.   And don't necessarily need 100% compatibility (and heck, some 7800's don't play all 2600 games (or at least easily because of some cart designs, so 100% is tricky).  

 

And this is an option for those...

 

More options are good.  But that doesn't mean that those options will work for everyone! ;-)  And that is fine...

I don't disagree :) but my marketing strategy mind is at work...and things aren't adding up LOL oh well. I love that this is even a thing and hope it continues.

The target market is the same people who bought every single version of the Atari Flashback, and the same people buying all these new MyArcade devices. People that just want more boxes with Atari logos to put on the shelf no matter how bad they are at playing Atari games. If this thing cost twice as much and played half as many games as the compatibility list indicated there would still be the same number of people here defending it, saying maybe if this one sells well enough they'll release a good one next year.

Here's a crazy idea:  somehow get an insider to talk Atari into allowing bare metal homebrew carts for the system.  AtariAge and AtariAge members could make sweet ARM based games.  The 2600+ becomes the actual, real, not emulated 2600+ system.  Could probably use many of the development tools the Evercade does.

 

Anyone know of a high ranking AtariAge and Atari employee that can get this blessing?

Maybe somebody here can dump the home brew carts and we can start a collection.

Assuming the original programmers are OK with it...
Might be good to see whether some of the original programmers come up with an alternate method to get the ROMs.
Either just offering them or a digital purchase option...

Most homebrew cartridges should work.  It's mainly the newer ARM-based games that are the issue.  Most of those are Champ Games... who have the ROMs available for purchase.  They also have Demo ROMs available.

Now you just need a way to load them onto the 2600+.

The Atari 2600+ uses ProSystem 1.3e emulator for 7800 games.

 

@Trebor tested 110 games for 7800 under ProSystem 1.3 Core via RetroArch. Most are 7800 Homebrews games, including some on sale in the AA store.

 

Test Results:

- 20 games = Black screen

- 6 games = No audio / No music / No sound (POKEY or TIA)

- 36 games = Works with issue:

graphic issue

graphic corruption

speed / timing issue

enemies absent

player will not move

sound issue

POKEY notes incorrect

- 1 game = Needs light gun support (Sentinel)

- 49 games = Works without issue

Not a great showing for the 7800 Homebrews to state the least. Best we can hope for is Atari integrating the updates readily available via JS7800 posted sources, which several from the community have assisted with updating.

Work would be needed to support homebrew mapper schemes with my dumper. Currently, my dumper in theory supports all the classic 2600 mappers (in practice it's only been tested with two, and there are probably bugs), but for any different mapper one would have to add code. (One could add code to auto-detect the new mapper, but I would be worried that this could break the auto-detection for one of the classic mappers, which are my priority. Probably a better solution would be to add code for the homebrew mappers that need to be manually set.)

Yeah, don't do this unless you want to discourage homebrew authors from continuing to develop new games in the future.  In other words, please respect homebrew authors' wishes on this front.  And certainly do not discuss dumping and sharing binaries for homebrew games here on AtariAge.

 

Thank you,

Will Star Castle homebrew or anything 2600 or 7800 bought from Atariage be compatible with the Atari 2600 +?

Many games will run, not all of them, but we are working on improving compatibility on this front. The biggest battle will be over Melody-based games, but we're confident we will ultimately be able to get those to work as well.  We are working on a "Atari 2600+ Community Compatibility List" and should have an initial version posted soon (both here and on Atari.com).  Ben from Plaion and I are currently working on getting most of the AtariAge 7800 homebrew games working, and I'll solicit help from the community in getting non-AtariAge 7800 homebrews running as well.

I don't like modding my vintage Atari systems.

I use a $3 coaxial RCA Adapter to get my old Atari consoles working with a modern TV.  As far as I know, modern televisions can still tune into channels 2.0 and 3.0 just fine.  At least all of mine can.

I believe that @Albert confirmed that some of them did work, just none with melody boards. It has been discussed in other threads.

:o I can’t wait to see Space Rocks, etc., running on the 2600+. Btw, has anyone tried the 7800 homebrew Asteroids Deluxe? I’d like to know if it’s currently compatible with the 2600+.

It doesn't currently work with the systems that are shipping, but it does work on newer firmware. :)
