I have acquired an 'untested' Marble Madness cartridge. TTL version
I am testing this in a working system 1 cab with Road Blasters.
First, I tried to just install the cartridge and see what would happen. The CR6 led on the top of the System 1 main board was flashing opposite as was this screen http://i244.photobucket.com/albums/gg30/railwarrior/marble madness/marblemadness001.jpg
I removed the board and removed and reseated all chips. Reinserted and got this 'Galaga-like boot' screen.

The CR6 Led is not lit. It just sits there 'cycling'.
I reinstalled Road Blasters just to double check and it works fine as before.
Any rom/socket locations to check first? Suggestions?
