the previous version of the refueling tunnel I posted on Atariage was, interesting and fun but it really did feel right, it just didn’t feel cannon. here is a picture of a new version you move through more like the original tunnel on the TI99 version. Difference, the tunnel stays stationary while your ship moves along. when one tunnel is complete, the next pops up.
here is the animated version on Atariage http://atariage.com/forums/topic/271220-back-to-parsec-for-2600-and-making-progress/?p=3877670
