MegaMari - 25 Mushroom Code - Part 01 

Entering 25 mushrooms into the password screen brings you right to Patchouli's fortress, without any weapons or items except for the broom. It's been done before (by 13/f/cali), but I thought I'd give it a go.
The 8-bit Necrofantasia mix was done by IKA, of Rockman No Constancy fame. You can get the NSF at his website.
