So I've mostly been playing TGM on my old desktop with a CRT, and I just got a real TGM board & a Sega Blast cab... But sometimes you wanna play on the go! Right now I've got Tetris Plus on my old GameBoy Pocket, but I miss having wall kicks. My laptop is a first gen Macbook w/ retina display, so it's hilaribad for Tetris, or any other kind of game. I mean I've made it to S8 with that much screen lag, but that's not the point. What kind of laptop will have the least amount of screen/keyboard lag & still run TGM fine in MAME? Preferably Windows & the smaller/cheaper the better.
