Maybe?

My only thought is incase I have done something wrong or one of my components is not behaving. Although if that was the case I think it would not be working at all.

Good luck and happy soldering.

I'm going to now retire from the Atari workshop with a G&T to pour over the schematics, pinouts and data sheets.

Yes its odd. Its bit like Smonson's HDMI/DVI adaptor. Magic Pockets works fine but desktop keeps rebooting.

Yeah thats odd as well..

There is the thought I guess that the 32Mz clock might need inverting.. but that would be assuming data was latched as it was changing.. which might explain the desktop, but not why the game works.

Its odd when you first power up, only white at the top where the text it...

First item between Falcon and board schematic

Falcon has pull up R503 on pins 15 & 26. Board schematic goes straight to Vcc
