/*
|
||||
* This l0dable by Benedikt Roth and Stefan Tomanek serves as your main
|
||||
* viewscreen, displaying your nickname the way you want it, and lets the
|
||||
* stars zoom by. You can accelerate your vessel by pushing the joystick
|
||||
* upwards or bring it to a halt by pressing it down - leaving your ship
|
||||
* drifting in the endless space. Attach two LEDs to the modulbus
|
||||
* connectors (SS2->GND, SS5->GND), so your r0ket can light up its nacelles
|
||||
* when breaking the warp barrier.
