Code Request (Force Backwards Camera on DS Twilight House) - JimmyKazakhstan - 07-16-2020

Hi. I am in the process of attempting to recreate Mario Kart DS Missions in Mario Kart Wii's Mission Mode. It has been going very well so far, However I could not manage to recreate Mission 1-6. Where you have to drive backwards out of Luigi's Mansion.

The closest thing to this is the "Force Looking Backwards" code. My request is a code that enables this code, but only when playing on the DS Twilight House slot.

The reason for it being DS Twilight House is that I plan to recreate the Missions on N64 Banshee Boardwalk and the track will use the SNES Ghost Valley 2 slot

Try this. It works for me on the Wii (USB Loader GX, default VBI hook). Haven't bothered trying it on Dolphin.

Thanks, But I already found a solution.

Hi again. Do you think you would be able to make a PAL Version of this? I don't have enough asm knowledge to do it myself.
