asm that allows for variable drop amounts, using the enemy headers 16h entry, which is normally unused
and distributes the drops based on the enemies width and height
the image is an exaggeration of its purpose, to showcase the distribution of drops
normally youd only want a few extras
I wrote this because I disliked how bigger enemies only ever had a single drop (sans a few rare examples like mini kraid, ninja pirates, and metroids)
