*Stellar cartography* that I have done, as I have the other two Gradius 3 secret level maps, all three Gradius 2 MSX secret level maps, also the INNER CORE level map from that game, and the Egyptian level of Life Force NES (the latter part of the level, with the maze plotted, along with the hidden-power-ups).
All of these are high quality. I checked the location of each bonus and enemy numerous times, though I might have made a mistake here and there. One thing though, the Gradius 3 SNES maps lack identification of the regenerating point bonuses. Even though these bonuses appear on the map, they are identical to other bonuses, and as a result, unmarked.

If anyone wants the other maps I have, just let me know. I'd be happy to give them out to anyone, for whatever purpose. If you use these on a website, please credit them to-
