Performance test

Find out whether your computer is fast enough before you install. Unpack it, put the firmware into the same folder and run virusTestConsole. It plays the factory demo song. The Virus TI runs two DSPs at 133 MHz each and needs a combined result of 266 MIPS or more. The Snow has one DSP at 163 MHz and needs 163 MIPS; the test cannot run in Snow mode yet.
