PC 25th Anniversary was my favorite Trek game ever. It got the whole "exploration, conversation, wonderment" thing down cold, whereas nearly every game since has revolved around combat, which just doesn't quite work.
Gameboy 25th Anniversary was the first video game I ever owned on the first video game system I ever owned... and it was ridiculously hard to beat. :P Never did get past the third beamdown...
Enter 1336.5 as the Stardate in the continue menu to go to the 4th map with 3 ships. If you have the Game Genie for the Game Boy enter these codes for the following effects:
Infinite Ships
006-E8B-19E
Infinite Torpedoes
007-02B-19E
Don't say I never did anything for you.

P.S. This game is hard as Hell. It took 3 years to finally get to and defeat the Doomsday Machine. Why has there never been another Doomsday Machine story in the canon? That thing was awesome!
