Hmm, okay. After byteswapping and reflashing P1, I am getting the system booting into a garbled display that seems to cycle between three/four different (garbled) screens, with visible transition effects going on..... I'm not quite certain what DDP's attract mode looks like but this sounds like a step in the right direction at the very least. Before byteswapping I was reliably getting the PGM to boot into a blue service menu (it seems like "blue menu" means "cart detected" where "red menu" is "no cart") so I think I might be on the right track? Going to redo the tile EEPROMs when I have the time and see if that gets me anywhere.

I think quite a lot of UI is done with sprites, so make sure you try to go into the level.

Hi - I think the OP should be updated with instructions to populate R2-R4 with pull up resistors... I couldn't get the skip BIOS functionality to work until I added those in, and nothing in the original post says anything about putting resistors there.

I did a update video on my YouTube channel about the extra pull up resistors....

You only have to use them if your not using the Atmel part. I have had NO issues with Atmel. Lattice was a different story!!
I have videos on all the aspects of building the Fluffy PCB for yourself...

Also, if you're sure that you'll never use the jumpers you can hardcode them in the source code for the gal.

Yes, problem was I was using a GAL with the pin keeper. There was info about it, but it was buried several pages into the thread.
Thanks for updating the OP.
