Atari 8bit/5200 collision?

[Ecernosoft]

Hello!

I know the 5200 and 8bit have hardware collision and I know about Hitclr, but what about the other registers?

 

Can you give me the names and what they do? 

 

Thanks!

I want to make ICT5200 but I'll need these registers.

GTIA starts at $D000. For example, $D003 is

(R) Missile 3 to playfield collision.

And so on.

I'm dealing with 5200 so GTIA would be $C000.

Also, how do I disable the color changing after said amount of time?

Yes, so $D003 maps to $C003, etc...

On an 8-bit that would be "poke 77,0"

but I assume you mean the 5200 again

 

Is there anything somewhat like a mapping for the 5200?

I'm using assembly, so does the GTIA have individual registers for every sprite (Ex. 1 register per sprite) or does it have one register per collision (Ex. P0-P1, P0-P2, P0-P3, etc)

GTIA = $C000-$C01F on 5200, $D000-$D01F on 8bit

It may be worth you having a look at this :-

 

Although it's for the 800 and you know the difference of the addresses, the register values will be the same

Each register is detailed
