Did you know the spine design on Hucard cases depend on the publisher?
Hudson Soft(Old case): Dark blue Hucard logo with Hudson volume number
Hudson Soft(New case): Blue Hucard logo with Hudson volume number
NEC Avenue: Purple Hucard logo with AV logo
Konami: Red Hucard logo with Konami logo
Namcot: Namcot logo
with "PC Engine" in katakana
Masaya: Pink Hucard logo with Masaya volume number
Sunsoft: Dark purple Hucard logo with Sunsoft volume number
Know any others?
This was a pretty cool idea, however some companies just had to ruin it by replacing the Hucard logo with their own for some added inconsistency. Looks like all CD, SCD and ACD cases didn't have any variations though.
