Just came across this old page with a bit of info I didn’t know: In Super Swing Golf: Season 2, each character had a costume based on old Tecmo NES games. Here’s a gallery of them, courtesy of Siliconera:
Ken – Solomon’s Key
Erika – Tokobot
Daisuke – Mighty Bomb Jack
Cecila – Rachel
Max – Tecmo Bowl
Kooh – Ayame
Arin – Pixie from Monster Rancher
Kaz – Rygar
Varthall
