So here I suppose I'll upload any weapons and other stuff I'll make for fun, so here goes nothing!
Missile Barrage

This weapon launches 5 missiles that home in on the enemy, but it has a very low ammo capacity so use it wisely!

This makes weapons appear on the automap. It does not show items such as E-Tanks, W-Tanks, Treble Sentries, Yashichis, etc.

Yashichi Finder

This shows you where the Yashichi is on the map, if there is one. This may or may not be compatible with Mega Man Powered up or Chaos Generator, but I haven't tried yet.
