2600 Pitfall Finishment


Propane13

Recommended Posts

2 Questions:

1- I believe I read an article here at Atariage.com that mentioned the first person to ever perfectly finish Pitfall (besides possibly David Crane himself) did so this year. Who wrote up that article, and where is it?

 

2) What is the maximum amount of points you can get in Pitfall? And, how many treasures are there?

 

Thanks,

That's not true, many people (including me ) finished the game with a perfect score back in 1982.

IIRC: 114.000, 16

Ah, here is the article: http://www.twingalaxies.com/cgi-perl/news_...llperfection.pl

 

I have a copy of JoyStik magazine (literally a copy-- a photocopy from the library)... the one where the Secret to finishing Raiders of the Lost Ark for the 2600 is printed, since I was so frustrated as a kid at figuring it out.

 

There's a section on Pitfall for the 2600, and there was a name listed and his score listed as a *perfect game*, and then I thought that this TwinGalaxies article was a complete load of gibberish. So, I wanted to find it, and see if in fact they'd missed any of these earlier perfect gamers. Would anyone be interested in the info in the article?

 

I bet Thomas could've finished it! Do you remember if the ending was special at all?

This was a championship with the perfect game winner being inducted into TwinGalaxy's hall of fame. It doesn't mention anything about being the first in the world to finish the game. If any of those photos or articles still exist, they would still need to be authenticated by Ron Corcoran.

BTW unless my memory is failing, the game continues to tick off the seconds after collecting the last treasure until the timer runs out (I think...this was quite a while ago). There is no "special" winning game screen. The tunnels must be used...sometimes in a criss-cross manner to save time (such as run left a few screens, descend, continue left, climb, then go BACK right a couple screens and descend before continuing left). Since Harry always appears on the left side after dying, I always went to the left when starting (the gators seemed easier that way as well...as will running WITH the rolling logs instead of against).

 

Cheat: Infinite time

Address $F723 E9 01 (SBC #$01)

change to -> EA EA (NOP NOP)

-using 2600gfx-

This is at lines 0723/0724

change |XXX.X..X| and |.......X|

to |XXX.X.X.| and |XXX.X.X.|

One final cheat for youse guyz:

Don't lose ANY points:

Address F3D3 : F8 (SED)

Change to -> : 60 (RTS)

 

-2600gfx-

03D3|XXXXX...| change to |.XX.....|

 

One final thing I noticed...

There is a BUTTload of screens before you get the last two treasures when moving to the left (silver & gold bar), with 20 screen in between them. My advise is to get those two by running to the right & then cut back left.

There were several perfect games with the remainig times listed in the German Activision Newsletter (I could make a scan). After the first perfect game the remaining time was used to differentiate the scores. I had a photo of my highscore, taken with an instant Kodak Land camera. Being taken from the market (due to Polaroid copyright violations) several years ago, that should prove authenticity perfectly.

 

Damn, I wish I could find that photo again!

No, the time (and the whole game) stops, else I would have had problems making the photo.

 

BTW: A complete disassembly of Pitfall! (by me ) can be found at The Dig!

It didn't stop using the infinite time cheat. I wonder if that same routine is used to check how many treasures are left (I couldn't see how, though).

*F71F

SED set decimal mode

LDA $D9 load seconds counter

SEC set the flag

SBC #$01 subtract a second **

BCS $02 if the flag is still set, skip the next line

LDA #$59 reset seconds to 59

STA $D9 ...and save

LDA $D8 load minutes counter

SBC #$00 subtract the carry...if any

STA $D8 ...and save

CLD clear decimal mode

LDA $D8 load the seconds counter

ORA $D9 combine with minutes counter

BNE $02 skip next if you still have time left

DEC $9E stop game

 

**this is the part that is patched with the cheat. The rest of the code runs as it should (it just doesn't subtract any seconds).

 

Here's your disassembly:; countdown timer:

dec timerLo ; 5

bpl .inTime ; 2³

lda #FRAMERATE-1 ; 2

sta timerLo ; 3

sed ; 2

lda timerMed ; 3

sec ; 2

** sbc #$01 ; 2

bcs .contMinute ; 2³

lda #$59 ; 2 start next minute

.contMinute:

sta timerMed ; 3

lda timerHi ; 3

IF TRAINER

lda #$19 ; 2

ELSE

sbc #$00 ; 2

ENDIF

sta timerHi ; 3

cld ; 2

lda timerHi ; 3 any more..

ora timerMed ; 3 ..time left?

bne .inTime ; 2³ yes, continue

dec noGameScroll ; 5 no, stop game

 

Looks like time keeps ticking to me. I couldn't find a "all treasure found?" routine. Looks like it only quits when the timer runs out of bits.

 

Note : your trainer mode is doing about the same thing my patch is, except with minutes instead of seconds. Does the game keep going in that mode as well?

Oh, it's there. Weird...the game didn't stop when I patched it. Is it because the timer is always at 20:00 using my patch?

 

.contCollision:

lda yPosHarry ; 3

cmp #64 ; 2 Harry at underground?

bcs .checkWallHit ; 2³ yes, check wall

lda atLiana ; 3 no, Harry at liana?

bne .endCollision ; 2³ yes, skip

lda sceneType ; 3

cmp #CROCO_SCENE ; 2 croco in scene?

beq .endCollision ; 2³ yes, skip

cmp #TREASURE_SCENE ; 2 treasue in scene?

bne .noTreasure1 ; 2³ no, skip

jsr CheckTreasures ; 6 yes, check if treasure was found before

bne .endCollision ; 2³

sta treasureBits,x ; 4 clear treasure bit

dec treasureCnt ; 5 all treasures found

bpl .incScore ; 2³ no, skip

dec noGameScroll ; 5 yes, game finished!!!

Thanks, but that was 20 years ago when I was young.

And I played on a PAL system, so it was a bit easier (slower) than the NTSC version.

Nothing special, the game just completely stopped as it normally does, when you're running out of time or got all treasures.

The total score is 114,000. You start with 2K. There are 4 different treasures - 8 of each, for a total of 32. Points for each are:

 

DIAMOND RING = 5000 POINTS

GOLD BAR = 4000 POINTS

SILVER BAR = 3000 POINTS

MONEY BAG = 2000 POINTS

 

If you collect all 32 within the 20 minute time limit, the timer stops and the game just ends.

 

Btw, the Twin Galaxies champ certainly isn't the first person to play a perfect game, he's just the first person to be "officially" recognized for it.
