We were quite surprised to see that the new DSi doesn't support R4 cartridges, but what came next really made us wonder – what is this device for ,then? Our colleagues from Kotaku.com have put together a video showing no less than 28 cartridges that won’t run in your DSi.

However, that doesn’t mean they’ll never work, as Nintendo will surely fix this in some firmware update, but the mere fact that the device is not supporting these is a big minus.

You can view the video here, although it might be a bit too tedious, so you might want to rewind to the end and count the cartridges yourselves.
