Synopsis
During The First Great Space War of 2100 reserves of titanium, the chief metallic element involved in ship construction, began to run out throughout the known universe. It was discovered by a savage alien race that the human colonised planet called Nevryon had large reserves of titanium ores.
They sent a fleet of vessels to take over this planet. They brought a large base in the form of a mobile asteroid and a huge alien beat came to oversee the action as well as a giant battle cruiser. After much resistance bases were set up on Nevryon by the aliens.
You are the people of Nevryon's last change. To succeed you must complete 4 very different missions: destroy the alien bases on the surfaces and caves of Nevryon and the asteroid, plus destroy from within both the battle cruiser and the alien beast. The aliens will attempt to attack and confuse you with every type of vessel they possess. A quite different piece of atmospheric music will be played to help you on each of the 4 quite different missions.
You begin each mission with a standard short range V5 Fighter. Anything larger would undoubtedly mean detection and death before you could even begin. However, once in the thick of the action, your fighter is able to collect and use a large array of extra weaponry and shielding. You are on your own but you will not be forgotten......

Thanks for this one
It's not behaving on my Pi, it's playable but there are graphical issues. When the logo scrolls up on the first screen, the background is corrupted with magenta bars. The flashing cursor remains at the top left.
Then there's text missing on the menu and the options screen is blank. If you start the game, iirc it usually pops up some brief intro text or something until you press fire but this doesn't appear.
In game, the status bar doesn't appear, I still see the Start/options box where it should be.
The game itself seems fine, I can play it with an Xbox 360 controller and die. A lot.
Grabbed from Packman along with ADDFS 2.85.

When I play tested on a Pi3, I did notice some background stars seem to stick on the screen, but nothing this bad. From your description it sounds like it may not have allocated the screen memory correctly.
Could you try the following and see if it makes any difference please:
F12
Dir $.Apps.Games (or wherever you installed it)
Echo <22><0>
!Nevryon
EDIT: I've taken a quick look at the game code and the first thing it does is turn the cursor off, which doesn't appear to work depending on the video mode it was launched in. It also performs a very odd check on the launch mode before defining the colour palette, which doesn't look right to me as it should be changing to the mode it wants before setting the palette.
If left on demo mode it does eventually crash - I'll investigate and figure out what needs changing to fix all these issues.

I also had weird graphical issues on Nevyron on a physical machine similar to this, unless I launched it in Mode 15
