[stella] Star Fire: 1 step forward 2 steps back :-)

[Manuel Polik <cybergoth@xxxxxxxx>]

Hi there!

Yet another Star Fire update. But this one is rather 
special I think. I ripped the kernel into pieces and 
then rebuilt it, allowing something really cool!

At least I think it's cool :-)

It's all possible now by using the Battlezone trick. 
Believe it or not, but I managed to clear enough cycles 
in the kernel for adding this:

; Reset stack to RESBL
    TXA                 
    LDX #$1F
    TXS
    TAX                 

; Draw starfield
    LDY vline
    CPY yposBackup+2
    PHP
    CPY yposBackup+1
    PHP
    CPY yposBackup
    PHP

:-)

On the other hand, I decided to can the Meteors scene. I 
never managed to turn it into something fun to play and 
it never really fitted the engine, causing too much 
internal trouble, and severe flicker.

Yet the meteors aren't totally gone, but see for 
yourself.

I'm concentrating on finishing the game now, but I fear 
I can't keep the X-Mas dealine, I'm sorry.

Greetings,
	Manuel
