// Description:
// This test assumes the following setup:
// EComRomRslvrExampleOnC on C:
// EComRomRslvrExampleOnZ on Z:
// The tests work by checking that the correct implementations are chosen from two plug-ins, one on C:, one on Z:
// Implementation:		On C:					On Z:								Expected result:
// 10009DC6			version 2				version 1							ROM resolver selects version 2 on C:
// 10009DC7			version 1				version 2							ROM resolver selects version 2 on Z:
// 10009DCF			version 1				-									ROM resolver does not return this
//
