They aren't necessary, but they make the templates look better. =P The first idea was to use sprites, but as there are more sprites than mugshots (Cut Man for example, and he is missing the Game Boy, Pokeroku and Soccer sprites) and their size are rarely the same (small / mid / big. Excluding others)... And some bosses have 2 or more mugshots, basically all from MM1-6 (Wily Wars, SAR, RCW and Soccer) plus Tengu, Astro and side-games like Board and Soccer in the original series, some from MMX1-3 (Xtreme1-2) and other games. Unfortunately, some also don't have more than 2 mugs. Weapons have even less icons, but there are a few extras like WilyWars/Rockman Complete Works.
