I was so free to add your usual fields for player side and autofire. I don't know if playing as P2 makes a difference, but it sure makes a world of difference to play with autofire. Also note that this is an ALL as opposed to an ALL! or something like that; the game recognizes your clear as you can see by the picture, but I didn't manage to beat the silly extra stage and can't be bothered to do so. This score is rather solid since I didn't lose a life during the main game (which is worth a lot) whereas beating the Special Stage does absolutely nothing for your score, really. It's also remarkably stupid.
Anyway, from all the complaints I've read about this game on the forum, I was expecting something horrendous, turns out this game is good. Not great, some of the later bosses prove to be a massive fly in the ointment (check out that amazing barrage from the fourth boss that leaves you no option but to bomb), but nonetheless far above average, I've played much, much, much worse. No idea why it has such a bad reputation, there is no good reason for that as far as I can tell.
