How do I downgrade to LJP RC8 to play Mario Kart?

[dilbert]

I have got the LJP RC8 to load, but it is saying I have the wrong .zem files and "version got/wanted:0500/0400. When I go to load the .zem files to the card, the don't load and it says they are not supported.

Do I need to delete all the other .zem files off my card?

Anybody have any idea?

Thanks!
