Wow I'm speechless.... It works! it really works!.. I don't know what kind of sorcery you pulled there but amazing work!
My hat's off to you sir!
Now, I'm have this weird issue with the rom "Antartic Adventure". For some reason when played through this setup on the Adam computer, the game loads fine but once the actual gameplay begins, the screen cuts off like if its going into a weird video mode. While in demo mode, the screen comes and goes depending on what part of the demo is playing, but its running in the background the whole time. Any ideas to what might be happening?
The thing is, it plays perfectly fine on my Expansion module #3 attached to an AV modded Colecovision system.
Edit: I had the Adam setup connected via the Composite video/Audio cable and then switched to the RF modulator, it plays great on RF. The Composite video output signal most be weak.
