    void UI_DisplayDownloadInfo(char* downloadName, float centerPoint, float yStart, float scale);
    __call(0x539363, (int)UI_DisplayDownloadInfo); // Smaller download text.

    void UI_DisplayDownloadInfo(char* downloadName, float centerPoint, float yStart, float scale) {
        void(*original)(char*, float, float, float) = (void(*)(char*, float, float, float)) 0x538AF0;
        original(downloadName, centerPoint, yStart, scale); //causing crash
