The FDS version is identical to the NES version except for better music.

i forgot just how quick the enemy formations arrive in second loop.
Some stages are relatively easy to point scab on indefinitely, while some are very difficult. but I didn't do that this time. Note that waiting to collect the super shot after collecting the double shot is not point scabbing.
A few new tips.
1) Sometimes if you miss a ship or two you can get more super shots. sure you lose out on 4000+ points for missing a formation, but you gain 1600 from getting the three sattelites, plus a super shot. And depending on your super shot meter you may need it.
2) on the stages with the enemy launchers in the middle it's safe to get each formation, because the stage will not end until all launchers are dead.
3) learn the chance stages. they follow patterns. once you have learned the patterns and timing you should perfect all of them, thohuh some are a lot harder without the double shot.
4) better to get the perfect bonus (20,000) then miss a ship to get a yellow 1000 bonus orb. do not chase them too much. DO chase down blue orbs, though (they will take out the ship you missed), as well as double shot and super shots (unless you are already full)
5) Super shots are best used on the following stages. you should never need to use one in any other.
a) third or later turret bosses. highest priority is taking out the ones with large bubble projectiles. you can take out two turrets at once if you aim well. if only the turret type for first boss and second boss ar left, you shouldn't need to use any more shots.
b) Earth boss second form use two on it.
c) use all remaining supershots on final boss from with eye open. once per eye opening. if you run out you will get another one when you die. Don't be surprised if you die a few times to this boss after he turns purple. This is what you got all those extra lives for.
6) if you die more then once on pluto boss, just reset. play on if it's only one time.
7) use savestates to practice jupiter boss. it IS quite learnable, but seems really unfair if you haven't figured out how his motion and swinging arms work. this boss is the first real brick wall that you simply NEED skill and knowledge to beat.
some of the later levels will cheat you out of a super shot, by offering a 1-up or a blue orb instead. you cannot stop this.
9) enemies all aim right for you. this makes their shots easy to dodge.
10) meteors tend to aim where you were a half a second ago. you can exploit this to help you get your formations.
11) The all 4 formations bonus (11,000) is not insignificant, but better to live then to die.
12) don't rush the ships boss at earth. dodge carefully! you do not have a time limit, so play st safe as possible. Also try to damage the blue and purple ship equally.
