I've made a load of mistakes, but the worst was getting rid of my NES Star Force prototype along with a shitload of NES games including Mega Man 1-6, Ninja Gaiden 1-3 (#3 being complete) and Castlevania Trilogy. Also had an Alladdin Deck Enhancer and Tengen Tetris (luckily no game stores took Maxi 15 cartridges or it'd be gone also). But yeh. Now it'll cost a load to get them all back.
