Well, I know it's not actually impressive at all.
But I finally tracked down a ROM of the original Super Robot Taisen for Gameboy.
Also managed to patch it to English with the help of the fine folks at Aeon Genesis.
Again, I know it's not really a spectacular feat- though I am a bit proud of myself.
P.S.- The game sucks by the way, but who cares? Otaku win!
