I just preserved a little piece of history today, as the only place I could find it was archive.org (during the October 9th security breach). I don't want this utility to disappear forever, so I have uploaded it here in the Downloads section of GBAtemp to preserve it further.
No modern Sonic era will ever beat this amazing cast of characters. I'm sad they've never returned, and all we have is the modern stuff. I wish they had stuck with the Mobius/Robotropolis/Knothole Village lore.
Testing the waters, I'm only listing one storage box type for now on my Etsy, to see what kind of interest there is. Holds 30 GBA carts. Comes fully assembled. $25 with a color accent, or just $22 for pure black. Gray lid foam included.
I printed it, and it came out flawless. Did a black base, with a red accent for the last 7 layers. Came out looking really good. This will be going into my personal Cube, and will be available in my Etsy shop soon.
