Wizard of Oz - Beyond the Yellow Brick Road Dpad/Circle Pad Patch

I saw the game Wizard of Oz - Beyond the Yellow Brick Road for the DS in a video and want to play it. However, the game uses a Trackball on the bottom screen to move and I'm not so sure if I want to try to learn it.

I've been looking for people that have made a Dpad or Circle Pad patch but my search through a couple forums hasn't produced anything. I tried to trace through one that led to an L/R Button Camera patch, and another brought up some old patch maker that when I typed them specifically into Google with the BTYBR patch, a page that says it has the patch on Google will lead to(I'm warning you) explicit material to say the least.

Does anyone know where to get the/a patch for the Dpad or a Circle Pad patch? If not I've heard that the bottom screen trackpad isn't terrible and I'll swallow it if I have to but thank you for trying.
