What is the difference from the blue and red logo galaxian?
Because on some multicarts i have it is blue on some it is red ( on some there is no logo at all but this is not the question here  )
There has to be difference or not? Because i could not see difference between them...
On other games like the blue logo pac man he moves faster and on the no logo version of pac man you beat all the stages in seconds because the yellow balls don't disappear when collected... but with the blue and red logo versions of galaxian i can't see the difference

I think in the "red logo" version (looks orange to me) the player's shots are a lot faster, making the game way easier than normal.

That is '1989 Galaxian' a.k.a. 'Super Galaxian'. I love that version enough that I made a standalone cartridge of it.

In the normal 'Galaxian', you must wait for your missile to clear the screen before you can shoot again, whereas in the 1989/Super variation, you can file many shots in succession...
