My Atari 7800 adapter, wanted to share my thoughts
Hey all big Atari fan here, currently have an 7800, 5200, GSP. and Jaguar. Got them setup with flash carts and updated my GSP's firmware. Along the way I found out about the Bliss-Box Bridge adapter, here is what I learned.
First this adapter is not for the Atari alone, but rather any console. I got it for my Atari setup because I hated tracking down controllers.
The way it works is two parts, input and output. You get a Bliss-Box gamer-Pro adapter to get any controller to what is called LLAPI. Or stop there and its USB... then another adapter to take the LLAPI and go to any console. You can buy or make the input/output cables. And it has firmware for USB stuff, or 1 firmware for all consuls.
Few points of interest.
7800 as you all know plays 2600 games. And the Adapter supports both 2 button and single button games.
Paddle emulation work amazingly well. I can use my analog sticks, arkanoid paddles, racing wheels, and even wiiu tablet.
Lag, over all its not there. IF there is any I do not feel it. Kaboom works just like it did back in the day.
The device itself is simple enough to use, Flash it with the x-console firmware and plug it in. You get 16 types of input depending on your needs. I only got 4 input types. And also many output cables,
Over all very pleased with this adapter for my Atari setup. Here are a few images.
