So, the 5.89 isn't possible because Dragster's timer skipped every tenth of a second or something? My certificate was number 6,540! I wonder how many tan certificates Activision made it their first run.

The certificate says that I got a time of 5.89 seconds. You probably had to get below 5.9 to get the patch because I wasn't a good game player when I was 11.

I attached a picture of the certificate. At first I thought about throwing the certificate in to whoever won the Dragster patch, but I was afraid that this thing could unexplainably be worth something.

I put my old Activision patches on Ebay. But I have an Activision Dragster Certificate that was sent to be when I earned my patch. I didn't put that on Ebay, because I didn't think anyone would care what score I got on Dragster in December of '82! But...Is it something a collector would want for historical value?

Alright, My wife is making me sell some stuff in order to pay for some new baby merchandise! I have a 5200 for sale with 26 games, and a bunch of Activision patches from my parents attic. http://search.ebay.com/_W0QQgotopageZ1QQsa...osortpropertyZ1 Thanks for looking!

I didn't work on my hack too much since Nukey got everything worked out. I spent days preparing for hurricane Charley, and then had to tear everything down. Now I'm under orders to set up our nursery! I was trying to mess around with the Tarzan music, but I'm playing by ear and what I'm trying to do doesn't sound to good! When I come up with something presentable, I'll post a screenshot.

Beautiful! Thanks a bunch, Nukey Shay! As for the black pants being underground, I was planning on making the underground a different color. Maybe something in grey scheme. But your changes will allow people to get creative with changing Harry! I think that most people when they hacked Pitfall! didn't change Harry or just lucked out with a color that didn't make the game buggy. I know that when I was experimenting, there were colors other than black that the pants could not be if you wanted the game to work. Now lets see what I can do with the music (Probably nothing)

A lot of activity this morning! I really appreciate it! I just hope that my hack ends up being good enough to warrant all this research... I took Nukey Shay's "corrected source", and changed Harry's pants colors. Still sinking! At first, I had a totally different vcs.h file, so I got the latest one from the dasm page Hope this is it: ; VCS.H ; Version 1.05, 13/November/2003 VERSION_VCS = 105 ; THIS IS A PRELIMINARY RELEASE OF *THE* "STANDARD" VCS.H ; THIS FILE IS EXPLICITLY SUPPORTED AS A DASM-PREFERRED COMPANION FILE ; PLEASE DO *NOT* REDISTRIBUTE THIS FILE! ; I changed the TIA_BASE_ADDRESS to $30 and the screen rolls. So now I'm thinking that I'm not executing DASM correctly: dasm pitfall.txt -f3 -opitfall.bin

Harry still sinks when I gave him brown shoes! Most of Harry's climbing pants cannot be black. This is really frustrating! I can't help but think that there's something wrong with the disassembly. One thing that I thought was strange was that there are two animation sprites for the climbing Harry. But one sprite consists of 21 lines and the other has 22. The colors for the climbing sprites deal with 22 lines Can anyone try to get Pitfall to work with Harry having black pants? All you have to do to test it is have Harry go left!

Thanks for the suggestions! So far, no luck. I started incrementing the color values by 1, until I just started doing $05, $0f, $10, $15, $1f, etc. It seems that the only time Harry doesn't sink into the black swamp is when his pants are a color greater than $20. Another thing that I noticed is that I can have "Running Harry's" pants be black, but "Climbing Harry's" pants need to be greater than $20. Again, I'm just fooling around with the disassembly and looking for patterns. I do not know how to program in assembler.

I've been using Thomas Jentzsch's disassembly of Pitfall to change the sprites and the colors, but I have one problem that's stopping me from wanting to continue with my hack idea. It seems that when I change the color of Harry's pants to black, he ends up sinking in the black pitfalls when they are closed. Changing the color of the black pitfalls did not help. The only time when I stopped Harry from sinking was when I changed the color of Harry's pants while he's climbing to a color other than black. Can someone help me out here? I really need Harry's pants to be black for my hack idea!

I like it! I used to play Sky Skipper all the time when I was a kid. This is a neat spin on the original. Good job!

Well, I had a battleship in one of my submissions. I wanted to make something with a "Two Tigers" kind of vibe. Now I'm a bit anxious!
