Dreamcast-Talk.com

Hello,

I just finished one of a project that was close to my heart.
I wanted a BBA for my dreamcast, but seeing the abusive prices, I decided to find an alternative solution.

To find the solution without FPGA emulation, I had to go back in time in the year 2000, and look at what sega was working on, hoping to find something to reproduce the BBA ... and it seemed obvious to me that the Naomi as well as the 'Atomiswave are the big sisters of our dreamcast ...

So I discovered the Atomiswave, and I worked on it to understand how the beast worked ... like the dreamcast!
Yes, the atomiswave is neither more nor less than a dreamcast in which we removed the GDROM to put a cartridge port
So guess what? the removable network adapter in your atomiswave ... it's a BBA: autop:

EUREKA, I found it!
It's a world first, it's MADE IN FRANCE

It took me many hours of research and testing to trace all the signals, but I succeeded: honor:

Long live the dreamcast at 100Mbps

How much would you sell a kit for?

Nice work man!

Only saw your thread about this 2 days ago at Obscure. Still blown away by how stupid easy and foolproof this mod is. I still am shocked it is so easy to do. But the Atomiswave was practically a Dreamcast spec wise so it actually makes so much sense that Sammy would repurpose the same hardware in Arcade Cabinets.

That begs the question, why have those games still not been made to work on the DC lol? On the Naomi and Naomi 2 I can understand, it has more video and audio memory on top of standard memory. So good luck with that.

I saw that at obscure gamers, but I'm not registered there to comment. Very cool to see this actually happened. I am actually kind of curious how widespread these devices are. Especially since we have to sacrifice one device for another. I have seen them being sold on ebay now, along with a few AUS and JP sites selling them directly. How much time/money/effort will it take to do this mod? It may not be the "homebrew" BBA the scene has always wanted, but at least it's something.

Since we have DreamPis running the online scene these days, I really want to see BBAs be able to find their way more easily / cheaper into the hands of devs who need them.

It would be incredible to be able to manufacture to sell for an affordable price. congratulations on your dedication to the project.

Thank you all for your interest in my work.
I ordered some kits to assemble yourself, I will put them on sale soon.

You can get the communication boards for $20 US right now, free shipping! More than 10 available. Sold 4 in the last 24 hours. $20 BBA anyone?

Holy smokes, I'm sold on giving this a punt. Will be intersted in buying a kit when they go up on sale. Will keep a keen eye on this thread.

Ordered one of the $20 boards meantime. Love an excuse to get the soldering gear out.

Nice job figuring this out
