First of all, I'm Bob and it's a pleasure to meet everyone. I've already read the sessions posted on programming, it's quite interesting stuff, I have to admit I haven't seen programming before where you have to control the TV as well. I have a few questions (that have probably been asked before) that I couldn't find answers to if you guys don't mind. I've figured out how to assemble and disassemble binary files and edit them using DASM and Stella on my Mac. I know how to change graphics by utilizing a configuration file with the GFX command and changing around the hex values to manipulate the individual graphics. I am tinkering with Haunted House to learn how to mess around with 6502 assembly language better, and here are my questions:

-How do I change the colors of the graphics? Say the room's color for example.

-How do I know which addresses (or where in the physical layout of the program when disasembled) have which information as far as playfield, sprites, etc. For example, if I want to find out where the data is in the code for when the matches go out when the ghost shows up.

-How can I figure out where the gameplay values are, and how to modify them? An example of this would be to change the speed of how fast the eyes move in Haunted House.

If this sounds vague I apologize, but I'm learning little by little, and I really like it so I'd like to learn more. Maybe with everyone's help I can make my own hack some time. Thanks in advance.

Bob

I should also probably add that I understand that COLUP0, COLUP1, COLUBK, and COLUPF have to do with the colors of their respective parts, and I have the TIA cheat sheet that shows all the colors in hex format. My question with color is that throughout the program I see that the colors get set or changed at different times. How do I know when these are changing colors and what the criteria for this to occur are?

IMO this thread really belongs in the Hacks forum, since it's dealing with specific questions regarding Haunted House.
See also:

Otherwise:
COLUPF = any colour you like. Criteria = any condition you choose.
