[lencio]

Hi, I try to run Bomb Jack version for Atari800 core (http://www.atarimania.com/game-atari-400-800-xl-xe-bomb-jack_21390.html).
I try with all diferent combinations of ram (the game require 320kb), and the game not run.
I boot using, F9, F8+F10(for basic disable, 320k compy, Rambo, 512K, 1MB and the game not run. At first show the game screen, but the game not run.
