Savetz Posted May 5, 2016 Share Posted May 5, 2016 Rob of the Player/Missile podcast and I have been using his awesome Omnivore binary editor to reverse engineer Jumpman. We're slowly figuring things out, and writing a detailed document (26 pages and counting) that we will eventually release. In the mean time, I thought I'd share some things. Here are the three Mystery Maze levels with the mystery removed (screenshots and playable ATR files) less mysterious.atrless mysterious 3.atrless mysterious 2.atr 8 Quote Link to comment Share on other sites More sharing options...

Grover Torbel Posted May 5, 2016 Share Posted May 5, 2016 It's great to see Jumpman getting some love. This is definitely one of the classics on the 8-bit Atari computers. Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
firebottle Posted May 5, 2016 Share Posted May 5, 2016 Tried these disk images in Altirra... they load until sector 186 then you hear a scratch noise and the screen turns a red color. Doesn't matter what OS or model I use. Tried Altirra 2.50, 2.70, latest beta. But using Atari800Win 4.0... they work fine. Quote Link to comment Share on other sites More sharing options...
playermissile Posted May 5, 2016 Share Posted May 5, 2016 (edited) We went with the ATR image because of problems with Atari800MacX. I used the kboot header to turn an XEX into an ATR, so if you strip off the first 3 sectors, you'll get an XEX. I'm also working on writing my own boot loader to replace the kboot header because I can't figure out, and it's given me problems, too.

Mclaneinc Posted May 6, 2016 Share Posted May 6, 2016 Well done Kevin, Jumpman is one of the games that sometimes gets overlooked because of the simple graphics yet there's a devil of a game underneath, in fact I have 3 games I still play on a weekly basis, Jumpman, Spelunker and Fractulas.

Tempest Posted May 6, 2016 Share Posted May 6, 2016 Can this be used with Jumpman Jr. as well? I've always wondered how many variations there are for Blackout (I think two, but who knows?) Quote Link to comment Share on other sites More sharing options...
Savetz Posted May 6, 2016 Author Share Posted May 6, 2016 Can this be used with Jumpman Jr. as well? I've always wondered how many variations there are for Blackout (I think two, but who knows?) Jumpman Jr. uses a level descriptor which is kind of similar but seems optimized to save space. And all the memory locations are different. So the answer for now is that Rob and I intend to go down that rabbit hole, but that's a project for the future. We'll also mulling the possibility of porting the levels that were unique to the C64. By "we" I mean Rob, because I can't code -Kevin Quote Link to comment Share on other sites More sharing options...

Savetz Posted May 6, 2016 Author Share Posted May 6, 2016 No, YOU'VE always wanted to play the demo level. The rocket and other baddies in the Jumpman demo screen aren't included here. So I made it aggressive with bullets to compensate Play The Demo.atr 3 Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted May 7, 2016 Share Posted May 7, 2016 Very nice Kevin, looking forward to the hacking guide and don't forget to ask Randy / Randall why he stopped the windows version he was doing? 1 Quote Link to comment Share on other sites More sharing options...
Farb Posted May 8, 2016 Share Posted May 8, 2016 Wow, nice work! This is one of my favorite games of all time. I have to ask, does anyone have a trick for using the far left "up" rope in the first Mystery Maze screenshot?

+therealbountybob Posted May 8, 2016 Share Posted May 8, 2016 Hi. Here's the first new Jumpman level in 33 years. -Kevin After losing a man I had the ring appear in the gap right of the first platform and couldn't reach it. After you are out you can't restart? I'm enjoying playing these, you know everyone is hoping we on for a new game one day Quote Link to comment Share on other sites More sharing options...

But you're correct, it's currently not possible to restart the level once you're out of lives. Rob is working on fixing that in the level tester.

tcdev Posted May 9, 2016 Share Posted May 9, 2016 Good to hear you guys are reverse-engineering the original. I've been thinking about porting an Atari 8-bit game to the TRS-80 Coco3, and Jumpman was a definite candidate. A commented disassembly might just seal the deal!

eegad Posted May 9, 2016 Share Posted May 9, 2016 I think it's great that you guys are making some new levels for Jumpman! I LOVED this game back in the day. I think because it was kind of "plain" looking, and didn't have any cool background music playing throughout, that it didn't get the love it deserved. But as far as the old style platforming type games, it was one of the best to play, in my opinion. Mostly because it was somewhat forgiving, and fair....you didn't always have to hit the platform pixel-perfect. If you landed near the edge, Jumpman would just smoothly walk up onto the girder. Great game. Haven't played it lately, but I'd like to throw out one request/suggestion. Any chance you could hack a version where you could select the starting level? From what I recall, you could choose beginner, which starts on level 1, intermediate which starts on level (9?), or expert which starts on level (20-ish?). I always wanted to just be able to select whichever level I wanted to play (and I hang my head in shame if there was always a way to do this, but I never figured it out!). 2 Quote Link to comment Share on other sites More sharing options...

This week, Kevin and I will release a version of the game that will allow you to practice any level. I've just got to finish up the code for the new menu, and it will be ready to go. 3 Quote Link to comment Share on other sites More sharing options...

Farb Posted May 10, 2016 Share Posted May 10, 2016 I have no problem using that rope. I figured out the problem... I was performing the jump onto the rope and then not moving the joystick. It looks like you have to move right onto the rope once you land on it or you fall. Quote Link to comment Share on other sites More sharing options...
