Doom 1 gba has better music,and is lighter than the pc which really is good. doom 2 is ligter than doom 2 pc and well call me crazy but i think the gba versions of doom are the best. 32x has horrible sounding music,ps1 has ugly lighting,snes has bad viewing,jaguar and saturn are even darker than the pc version and the gba is lighter and less dark than the pc version so the gba version wins.
