KenJennings Posted April 17, 2020 Report Share Posted April 17, 2020 (edited) OldSkoolCoder presented a video on YouTube and source code on GitHub for a Frogger-like game written for the PET 4032 in 1983. The PET assembly source is here: https://github.com/OldSkoolCoder/PET-Frogger The OldSkoolCoder YouTube channel is here: https://www.youtube.com/channel/UCtWfJHX6gZSOizZDbwmOrdg/videos OldSkoolCoder's PET FROGGER video is here: https://www.youtube.com/watch?v=xPiCUcdOry4 Atari Assembly code is here: https://github.com/kenjennings/Atari-Pet-Frogger A video of the gameplay for the Atari version is here: https://youtu.be/UtNz5EE3xno ---------- PET FROGGER for Commodore PET 4032 (c) November 1983 by John C. Dale, aka Dalesoft. Ported (parodied) to Atari 8-bit computers by Ken Jennings Version 00 - November 2018 This is the original program ported from the PET pretty much as-is. Version 01 - December 2018 This was re-tooled to break the code into modular functions and introduce frame-oriented timing. Visually still mostly the same as Version 00. Version 02 - February 2019 Version 02 expands on Version 01 with some Atari-specific enhancements. Custom Display Lists, redefined character set for better graphics, Display List interrupts providing color, coarse scrolling by Display List LMS address updates, joystick input, and a Vertical Blank Interrupt managing the world's lamest sound effects and music sequencer. Version 03 - August 2019 This expands on Version 02 with more detailed graphics via redefined characters sets, fine scrolling boats, Player/Missile graphics for the Player, more color, blah blah. The lame sound effects now include a buzzy motor sound for the boats engines. SELECT and OPTION keys can change the number of lives and starting level.

KenJennings Posted April 18, 2020 Author Report Share Posted April 18, 2020 1 hour ago, TrekMD said: Cool. Looks fun! Thanks! It's fun for about two or three rounds. Then starts toward tedious once you catch on to the rhythm of the fast moving boats. The original game was made by a high school student, so it is simple and has extremely limited goals. Basically, just a twitch game that looks pretty on the Atari until you get tired of it. Or like a human-interactive graphics demo. (It certainly isn't going to win awards for its sounds.) Mostly this is a mental exercise to see how much Atari graphical-ness programming could be worked into the game without substantially changing the game mechanics itself.

TrekMD Posted April 18, 2020 Report Share Posted April 18, 2020 Oh, one of those, eh? It still does look quite nice. Justin 1 Quote 🖖 Going to the final frontier, gaming... Link to comment Share on other sites More sharing options...
Paul Westphal Posted September 12, 2020 Report Share Posted September 12, 2020 Well for a low level programmed game, there is a lot going on, on screen, and has good color. Well done! Quote Link to comment Share on other sites More sharing options...
