Subject: [PATCH] GameINI: Disable Dual Core for Rally Championship

When selecting cars, this game crashes with GFX FIFO: Unknown Opcode. This is solved by disabling Dual Core, as the error message suggests.

There is no information about this on the Wiki, just a link to a gameplay on YouTube.

This is my first PR here and one of the first ones on GitHub. Due to personal issues I don't have much free time to dedicate to this, but I'm doing my best to get everything right.
