nlaunch Ndless lua_game gbc4nspire来自 http://www.cncalc.org/thread-8707-1-2.html
然后ndless.tco是百度里随便找的 v3.1_beta_r914
然后下了3.2的教师版连接软件 结果将ndless.tco拖到计算器里的时候就是没给我按两下enter的机会 直接重启并且电脑端显示则显示 experienced a problem while communicating with the handheld. A retry may be successful; The CX C472 is unavailable. Make sure the handheld has not lost connection.
怎么破?? 急求,马上就要考AP!
