I also have some old cases that are like UGCs in the overall construction, except they are sized perfectly for NES games. Therefore, they are about the same width, but they are shorter. They have no clips on the inside, but they still hold NES cases very well because the overall dimensions are about the size of an NES cart. These also do not have any sleeves and they appear as though they never did. If I remember correctly, my old video game rental store used to keep their NES games in these and I think I aquired these when they sold off some of their old stock.
