Creator of Julius here. Not specifically C, but you do want to have a language that's as close to the hardware as possible. Since Julius supports way higher resolutions than the original, the time required to draw the screen also increases: full-HD resolution requires 6.75 times more pixels to be drawn than 640x480. I've had to make optimizations to the drawing code to get a decent framerate on higher resolutions.
