Hey everyone, was looking for some info on a test cartridge my buddy and I found. We have quite a bit of Nintendo test equipment but have never come across something like this. It was a black blank sega genesis cartridge with a label that says Test Cartridge on it. Booted it up and it says "Get Ready" and plays a sound sample, along with the color screen and a simple test program for the controllers. Was wondering if any of you guys have any info on this, as we can't find any mention of this test cartridge anywhere. Thanks.
