/* Instruction timing */
In r008.5.14, MEM_WR has an OSD menu choice to switch between "quick" and "slow", "slow" mode does insert ONE WAIT_n during detection of MEM_WR. This switch exists because somes games are running in "slow" mode and others in "quick" mode. In fact it exists several instruction making MEM_wr, and adding each one ONE WAIT_n does result in different case of synchronization.
