Cruis'n USA

Cruis'n USA is an arcade racing game originally released in 1994. It was developed by Midway Games and published and distributed by Nintendo. It is the first game in the Cruis'n series and features locations around the United States. Although Cruis'n USA was advertised as running on Ultra 64 hardware (based on the Nintendo 64's hardware), it was actually implemented on the Midway V-unit hardware. The hardware consisted of a TMS32031 CPU clocked at 50 MHz, an ADSP-2115 DSP clocked at 10 MHz for sound and a custom 3D chip that could render perspective-correct but unfiltered quads at a high resolution (512 x 400 pixels).

Along with Killer Instinct Gold, it was planned as a launch title for the Nintendo 64. Neither game made it out for Nintendo 64's launch, however, primarily because the arcade versions of both games were done on hardware that was very different and somewhat more powerful than the console. Cruis'n USA, although impressive in arcades in 1994, got panned in 1996 when it was finally released on the Nintendo 64 because the port was less polished than the arcade version and its technology had already been surpassed by other games.

Addressing Low Framerates
Nintendo 64 emulation is strenuous for the Wii. Sluggish framerates can be improved by using Dolphin's options to overclock the Wii CPU (under Config/Advanced). A CPU Clock Override of 175% should keep the framerate at a stable 30 FPS (1 player only) with no noticeable side effects. 2 player mode required an even higher override of 250% to avoid slowdown on San Francisco; the most stressful track.
