* Copy CPCZVM.COM, ZXZVM.BIN and the game file (e.g. ADVENT.Z3) to media which has at least 64KB free. All of these should be in the same location. For Amstrad's CPM2.2 it It is advised to use a VENDOR/SYSTEM formatted discCPM+. CPM2.2 is supported but there is not enough memory. CPCZVM may not be compatible with other CPMs.
