From Dev-Scene
A simple memory test app based on the description of the tests performed by memtest86.
There are about five different accessories for SLOT-2 that feature RAM, including the expansion pak included with Nintendo DS Browser. They all have their failure modes. This program makes sure that your RAM pak is working fine.
The application falls back to testing 3 MB of DS internal RAM if it doesn't detect a RAM pak.
