Inspired by the "Game of the Week" thread, I pulled out Vigilante for the PCE. Beat that sucker (1CC, no, of course I didn't lose a single life).
Then I revisited Space Invaders HuCard, which I've been obsessed with, for some bizzarro reason. I like the updated version.
Of course, I couldn't turn off the PCE without getting some good old Gomola Speed under the belt. Damn, I love that game.
