Dino Crisis doesnt work on my DC, can anyone help?

[stingray2k]

I have a backup of Dino Crisis for the DC. It boots up fine and would appear to work because I can here sounds in the background.
Unfortunately there is no picture. I am guessing that this requires
some kind of RGB patch or something, can anyone help?

Please mail me on...
