Video Game to Computer Game conversions

[Castelak]

Are these worth anything at all? Today at the Salvation Army I found a Mega Man game for the IBM compatible computers (older ones =p) and a Double Dragon game that works with IBM, Amiga, Atari ST, C64, etc. $.50 each so I guess it's a good deal. o.o

I had an old PC compilation which contained Street Fighter I & II plus two Mega Man games (I forget which). I figured this might be worth a little bit and Ebayed it.

It fetched... £1! :D
