I recently rearranged my 8- and 16-bit systems so the NES, SNES, GENESIS and TURBOGRAFX-16 systems (+ others) were hooked up to my 27" tube TV. Previously I had a couple of those systems hooked up to the big-ass LCD in the living room, but they never looked right. So since everything is now being displayed properly on a tube TV, I went ahead and calibrated the TV again and went to town on old-school gaming goodness.
So to test the new setup, I played:
NES: Blaster Master, Gradius, Galaga
Genesis: Steel Empire, Castle of Illusion
SNES: Mega Man X, Gradius III, Pop'n Twin Bee, F-Zero
TG-16: Galaga '90, OotG (since I put in OotG I really haven't played anything else)
