just broke my current best score in Dimahoo by a small amount.. got 3x before the first boss, got both the fairy and the jewel, then got demotivated after dying once on stage 2 (I felt that I would need that life/bomb later) and stopped playing (though I still have the input file and will treasure it for some Ha ha, old chap! moments). Further demotivation caused by me having heard of the rank increase gained by completing sets, but never actually experiencing how noticeable it is, until now.
At least, I've figured out how getting the fairy from the first boss is done; once you know what attacks the boss uses when it first appears, and from where, you can safely time your charge level (and element) and approach. Also, for those who wish to know the charge order for the first stage.. it seems to be like.. lvl 1 (right after picking the first magic powerup) - lvl 4 (make sure to kill the goblins as soon as they leave the forest) - lvl 3 (focus on the tank) - lvl 3 (try to attack the arms of the metallic armor) - lvl 3 (on the same type of metallic armor) - lvl 5 (against the blue dragon, as it's leaving the screen)
edit:
here's the input file (made in lagless mame99p), for those who may be curious
