Thank-you for publishing this digital version as my original disk 1 got corrupted. It would be interesting if we could have a Metal Dust world championship or some other competition. I'm currently on level 3 on "Easy" (15 lives per continue). Also, fun fact, to enable the built-in cheat mode, just listen to the music on the title screen for a few minutes, then you have an option that allows up to 99 lives per continue.
