Converted the Konami System 573 Security Cassettes to use slots. The current setting is no longer saved, so the default cassette is "game". Some games have additional I/O connected via the security cassette, which is now hooked up when the cassette is loaded instead of patched directly into the memory map. If the game has a separate "install" cassette then you need to select this and hard reset (shift+F3 or select reset from the slot menu) before it will let you install from the CD. [smf]
