Given that you didn't state exactly what patch you needed, I did a somewhat general patch search, and found the only one where people mentioned it fixing any errors with the game. I found the patch on the manufacturer's site and managed to find the link despite it all being in Japanese then took the liberty of uploading it to Badongo. So, here you go the version 1.02 patch:

On the other hand if you meant an English patch I'm afraid there isn't any that I could see.
