Deliverance was really great, but... I saw it on C64 after emulation became extremely popular in PCs
And about Galaga, It was ported to MSX (as already said) but it was originally created to Arcades. I agree, it's one of the most popular games ever released!
*PS* Anyone knows what's the DTV Joystick (with "Sega" exclusively games, that in fact contain Amiga games???)
