thanks for all the feedback
i am very happy!
(where's the star field effect by the way? 
)
hehehe - a 3d starfield was the first i did, but i couldn't make the "fake 3d" look good.
and forcing the beam from star to star (for only 1 point) is taking a lot of "time"
i was (or am) also thinking about a star-wars scroller

Great stuff. Did you make some design work in advance on mame?
the programming is completely in mame - usually i change the game-driver source code for my needs (more rom, more ram, serial eeprom)
most of the time the emulation is good enough (no big difference can be seen)
but e.g. on asteroids it was completely different.
i programmed the avg straight away...something like...beam, go to position 100,100...draw a line to 200,200..and so on..
this works on mame..but not on the real thing... because the beam needs some time to go to the position..that is why (on asteroids) they added an "draw a not seen point vector" after the "go to" command that the beam has enough time to go there.
another thing difference is: if you draw a lot of text all around the screen, the beam needs a lot of time to draw it... on mame no flickering can be seen, on the real thing it starts to flicker because the refresh-rate goes down
but i must also admit: without mame - the developing would not be that easy!
Not only is the text scrolling, i see some familiar names passing !
The scrolling text are members here at DLF!
hehehe, these are the greetings - like in the oldschool demos :-)
