Bredok3D 737 integrated Checklist

Hi all,

In this video at the 3:46 mark you can see an integrated checklist. Does anyone know where to get that and how to integrate it into the panel? For most of the buttons on the MFD all I see on the screen when I click them is “inop”, yet in this video they all seem to work and bring something up. Did they work at some point and now they don’t? I don’t have the 32X or the Salty installed, which I know can conflict with this aircraft. Would the WT G3000 or G1000NXI mod mess it up?

Any information appreciated. Thanks!
