This is my first post

I love a very old c64 game: Cosmic Convoy but since is very difficult to play I've been looking for some tricks or cheat.
Unfortunately, untill now I didn't find any.
This is the link to get the game and where you can see a screenshot of it:
www gamebase64 com/game.php?id=1699&d=18
(remember to put the dot after www and before com)
I've only found the way to stop our convoy that is:
poke 25384,173
and the way to speed up 10 times the convoy:
poke 25367,10
There is a way to survive against the attack of the enemies (disable sprite-sprite collision) with some cartridge such as Action Replay but the problem is that our convoy can be destroyed before it reaches the destination and so game ends.
I had no success trying to disable sprite-background collision
Anyone can help me?
Thanks
