new pitfall hack


ATARI TROLL

Recommended Posts

If you really want to make it interesting, change some of the colors around. It's pretty easy with Thomas J's disassembly of the game, just look through the code, make the changes, and recompile it with dasm.

 

Here's what you should look for in the code:

 

; color constants:

 IF NTSC

BROWN           = $12

YELLOW          = $1e

ORANGE          = $3e

RED             = $48

GREEN           = $d6

BLUE            = $a4

YELLOW_GREEN    = $c8

PINK            = $4a

 ELSE

BROWN           = $22

YELLOW          = $2e

ORANGE          = $4e

RED             = $68

GREEN           = $56

BLUE            = $b4

YELLOW_GREEN    = $78

PINK            = $4a

 ENDIF

BLACK           = $00

GREY            = $06

WHITE           = $0e

DARK_GREEN      = GREEN  - $04

DARK_RED        = RED    - $06


; Harry's colors while climbing:

ClimbColTab:

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte PINK

   .byte PINK

   .byte PINK

   .byte BROWN
; Harry's colors while running:

RunColTab:

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte DARK_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte YELLOW_GREEN

   .byte PINK

   .byte PINK

   .byte PINK

   .byte BROWN

 

You can experiment with the color codes, but if you search the forums you can find a color chart to help out.

 

Make your changes, download a copy of dasm, type "dasm pitfall.txt -f3 -opitfall.bin" and you're all set. I've attached a copy of the disassembly to this post, however it's freely available at the Dig. Have Fun!

I've been working on a Pitfall hack using Thomas' dissassembly. After compiling it, I tried using Z26 and it was all funky. Invisible vines, no collision with logs, etc. So I tried compiling the unhacked file, and it did the same thing (should have checked that before I started working!) I found this old thread while looking for some help. I did everything you said, even using the file you posted but it doesn't work. I can compile other files so I just don't know what's wrong. Any ideas?

 

Thanks,

Keir

Question. Is this color chart for Pitfall ONLY, or is it universal for colors in ALL VCS games? :?: :?: :?: :?:

Thought I would add to this....Indiana Pitfall v.7 is a hack to the extreme 7th power. Meaning, It was Atari Maximus's Pitfall Trainer that I started hacking on way back when. Credit should be given to him where I failed to mention it above. So my Hats off to Atari Maximus. I like the unlimited lives and no timer. Gives my 2 1/2 year old a chance to play a game without the difficulty!

 

Cheers
