doubt I can complete the list, I'll try to keep it short
Chrono Trigger, Metroid, Super Metroid, All 4 TMNT Games (4 is awesome multiplayer badness), All Mega Man Games (X is sweet, I make that game look simple), Zelda, All three Contras ( I own 1 and 2
), Snake Rattle & Roll, Marble Madness, Arch Rivals, Super Spike 'n' Vollyball, Super Dodgeball.. oh man the list goes on! heh.
There was this one game for the C64.. I can't remember the name, but you were this little stickman that had to collect orbs. there was either a time limit or some other guy you had to race. At harder levels bullets would shoot past the screen at varying speeds. With a color monitor it was all rainbow colors
Oh one of the really hard levels was that it was invisible, and you had to creep along to show the board without falling off...... Soon after they shot bullet at you too.. heh
