To be clear about optional graphics, flash fish: Optional graphics are certain lvz files that are set as optional in rumble. If you have optional graphics off (Continuum Main Menu / View / Options / Other / "Use Optional Graphics and Sound") then you won't see the colored ships but the normal, default, ships. The normal, default, ships are then the warbird, spider and such because those ships have gotten a different "skin" that is the jav with another color. So.. Optional graphics OFF: You see the warbird, spider, shark, etc. Optional graphics ON: You see the colored javelins Why is this done? 1) For people that don't want to download the extra graphics that make the ships to colored javelins (around 1.025 kB, 1 MB) 2) For people that want to use their own shipset (you can download such from ssdownloads.com )
