So, I grabbed a hundred of these...
Cheap-O DS/GBA cases...and I gotta say I'm a happy camper. 30 bucks shipped to my house versus $28 to have 30 Nintendo cases shipped. 1/3 the price is fine with me, especially since I'm gonna hack a bunch of 'em up to figure out how to stuff other things in 'em.
Here are the big differences.
OEM cases are about a 90% warm grey, aftermarket cases are BLACK.

Missing logos, which is no big surprise.




The plastic sleeve is still PP, but it's much thinner. Probably about half the thickness. It's pretty much impossible to show in pics, but it's most definitely noticeable when you see and hold them.

Other than that, it's pretty hard to distinguish them from the Nintendo cases.


The only other items of note are:
- The cheap cases don't close as tightly as the Nintendo cases (they pop open with FAR less effort).
- The plastic is still PP, but it's a cheaper mixture. Normally I'd site that as an issue, but since I'm gonna hack a bunch of 'em up, it actually helps since it's a LOT easier to cut.
- And speaking of modifying them, there's a little support strip that runs across the top of the side opposite of the retaining clips for the games (see pic). On the OEM cases, it runs a little shallower. This doesn't affect the ability to hold DS or GBA games, but if you wanna mod them to hold GB/GBC games, then you'll have to cut the support down a few millimeters since both GB and GBC games are just a tad thicker, which is enough to cause interference.

Well, hope this was helpful for anyone who's interested in these cases
