I'm trying to copy spyro year of the dragon. i keep getting the "console has been modified screen". ive copied a lot of games before but this one and lilo and stitch I cant seem to get. Ive tried several patches but none seem to work. I get the patch screen but then a blank TV. I'm using a ps exchange disc which has always worked good. (I dont mind the extra time.) I'm in the USA so I use the ntsc patches. I have a psone.

Can anyone help?
By the way these game sare for my 6yr ood son!

thanks
