So I'm the owner of a bunch of game series, however some are for the famicom, which means that using them in the UGC's would result in either 1) flopping around for all eternity, or 2) foam strip tape everywhere.

Now I'm wondering how to solve this, the issue not only being the cartridge to case-ratio, but also the fact that I want my collection to look uniform. Is there a way to mod an UGC to hold two famicom cartridges, and then make it double/triple on top of that?
From what I've understood the doubling if the cases lead to wider cases, but not necessarily the room to store more games safely?
Grateful for advice!
