For Windows users, Kemulator is a powerful emulator that allows you to play Java games on a big screen. You can upscale the 128x160 resolution to full HD, but prepare for massive pixels.

To a modern gamer, 128x160 sounds laughable. For context:

// shift body for(int i=length-1; i>0; i--) x[i] = x[i-1]; y[i] = y[i-1];

long delay = 150 - (System.currentTimeMillis() - start); if(delay > 0) try Thread.sleep(delay); catch(Exception e) {} } }
