Wow. Thanks for reminding me about Datastorm, the first Defender come I ever played (Amiga, around 1992). I just installed the Amiga emulator fs-uae and downloaded the ADF file. IT WORKS. It's amazing how much detail you remember from a game you played when you were in your teens 30 years ago. That intro tune, man.. they really knew how to make music on those things. The game rocks too. I remember it being a bitch, and I just got my ass kicked a by it again. In fairness, I'm using cursor keys and right ALT.
