I really don't know why nobody has marketed a case that is empty of cart holders, that a cart holder can clip into. 1 mould for the case, then sell the cart holders separately that clip in.
Truly universal, and interchangeable..
Could do a range of different sized cases, that the different cart holders can clip into. Also, without using a cart holder the case can be used for peripherals, promo items, manuals, etc.
But, at this stage, I am not trying to throw more into the mix. I just want sega clamshells! 😜
