DPC+?

[Rabbit 2600]

Where can I get my hands on DPC+?

[+Gemintronic]

I think R.T. is compiling some information about DPC+

http://atariage.com/forums/topic/215256-need-help-compiling-and-updating-dpc-information/

 

I have no idea where the very, very latest DPC+ is. I don't think it officially got out of pre 1.0 status.

 

UPDATE: This topic *may* have it

This is the latest with additions and bug fixes, in Post 1.

Awesome, cheers!

The bB page has a growing section about the DPC+ kernel:

 

randomterrain.com/atari-2600-memories-batari-basic-commands.html#dpcplus

 

It tells you where to go to get the latest version of bB with the DPC+ kernel. This section also tells you where to get the latest version of bB with the DPC+ kernel:

Hm, I do have a question about multisprites in DPC+

Do I simply need to copy this and rename it player2 instead of player1? Maybe multisprites can't be multicolored?

[iesposta]

Yes. Coping should work. You do not need to define the same colors if they are not changing. Also sprites in DPC+ are right side up (there is a flip in VbB).

Set kernel_options has to go.

DPC+ has all that in already.

Scorecolor: is different. It is defined like playerXcolor:

Usually with 8 color values then an end.

Fractional data fetchers must be set before each drawscreen.

Bank 1 is filled with bB so you have to "goto LABEL bank2" after set kernel DPC+

See randomterrain.com for examples of DECFRACINC . Find one of my posts with .bas files and look at the top.

Ahh, cheers. Now I should be able to get things going =)

There's kind of a template here that you can use:
