Bridge interfacing with the PS2

It begins the PS2 portion of the Bridge. The first step was to analyze the live data. This was pretty straight forward and easy since I had previous experience with the Bliss-Box and the fact the protocol is just an SPI interface at that. Here we are looking at the live data.

 

Now here is something interesting I always wondered about…. Notice the gap from data? 16ms… Now it is interesting to point out this is a 16ms poll tied to the frame. USB could never do that from an emulator but it just goes to show 16ms is nothing. All you need to do is make sure the button data is polled at the right time. As we make out way further down the road with systems like the MiSTer, we will see that very thing happening, and lag will be no more.

Next up, some real emulation from the Bridge.
