21st November, 2022 - Release 5.01 (Multi-skin System + bug fix)
Implemented a series of new routines to allow adding new graphic skins to
the simulator and select the desired one at every game (from the
splash-screen).
The game is now released with two skins, one reproducing the regular release
of the game (with a few graphic fixes compared to the previous version),
and the other being a very rare variant featuring a display with very
different sprites - which origin is still a mystery. The latter is called
"VFD Revision D". Photos of this rare variant were provided by my old friend
Kevtris - thank you man!
With the second skin, two versions are made available: normal and zoomed.
Also fixed a bug introduced in version 1.01 of the game (eleven years ago!) that
caused the "thrust" to be completely disabled during Phase 4 of the game. I am
surprised this went unnoticed for so many years. Anyway, it's fixed now!

4th December, 2017 - Release 5.00 (Standard 5, complete rewrite)
Added a new option to the on-screen game menu, to enable the user to change
from fullscreen to windowed (shaped) mode on the fly; minor tweakings.

16th October, 2017 - Release 5.00 * PUBLIC BETA *
Officially released through an "open beta testing" program.

25th July, 2017 - Release 5.00 * PRIVATE BETA *

instructions manual; all of the skin options can be changed via the included
"config.ini" file; the visualization mode can now be changed to "fullscreen";
added a new key configurator panel (settings are saved into the system
registry); all game buttons can now be operated via keyboard, mouse and touch
screen; new splash screen; new "about" screen; minor fixes and optimizations to
the source code; added support for .png images; added on-screen menu to the
"fullscreen" mode; added option to the menu to allow the editing of the
configuration file; added "halo" to sprites to replicate the glow of the LED
sprites.

26th October, 2015 - Release S4/1.02 (Standard 4, larger manual added)

Completely rewritten source code in order to do major optimizazions, fix bugs,
etc. Included new much more detailed instructions manual than the previous one.
