I choose the covers that I liked the most from the cover project website. Mostly the Australian PAL releases and a few American NTSC releases, if they had more vibrant colors. I don’t like the European PAL releases much, with their black borders and black spines. There is some color difference. Some are brighter than others. Luckily, the most important ones (to me), Super Mario 64 and Banjo-Kazooie look the nicest. Those will definitely get displayed facing fronts forwards. Of course Ocarina of Time is also a favorite. But I have never been a fan of the artwork. I might switch it to the more black and gold cover in the future.
But it ain’t all N64 games that I have put in a custom case. There’s also a SNES game.
Now I have to make a space for them in the gameroom. And I have to buy a new printer cartridge to do the Atari Lynx covers.
