Blazing Lazers -- I played that game to death when I first got the system (my brothers and I couldn't afford to buy new games for a long time, since we spent all our money on the cosole).
not that u asked, but here are my 2 cents:
1. at many points in the game, you need to shift your speed (select or start button?), and you need to do this according to the weapons you have. For example, at the end of the game (last stage boss rush), you may only have the pea-shooter... so sometimes you need to put your speed up to the MAX and quickly fly back and forth (horizontally) to take out the enemies. other times, you need to slow down to navigate the bullets....
2. BETTER TIP: The secret is to keep shooting the power-ups that "cycle" through I, II, III , IV.... keep shooting them and they eventually turn into a blinking rainbow sphere.
grab this sphere and (1) all enemies on the screen disappear and MORE IMPORTANTLY (2) the next time you die, you'll "re-spawn" and continue on your journey uninterrupted (instead of restarting at the checkpoint).
On default, I get like 15-20 of these "re-spawing" power-ups. Even if you get sloppy and die towards the end of the game (the boss rush), you won't have return to the checkpoint and keep playing the bosses over and over.
the last boss is pretty easy on default. find the speed that is appropriate, though.
