General Chat - ZSC / Re: Folyami ratings monthly up...
Last post by Duplode - August 22, 2026, 08:05:39 PMBefore August wraps up, here is the ZCT300 update of the rankings! We gladly saw many comebacks for #300, with afullo, Bonzai Joe, Daniel3D, Friker, KyLiE, Overdrijf, Shorty and Zak McKracken back into the current ranking. Some big swings in such a busy race, with the biggest gains being by Ryoma at +59. Personal best ratings were reached by Alain, MiDiaN (into the historical top 3!!) and RC Bandit. Below is the updated evolution chart:

Competition 2026 / Re: Cars and rules for 2027
Last post by Victor Narl - August 22, 2026, 01:10:37 PMI propose a rule starting next year to take into account team points for all riders, not just the top two. This will increase the interest in team competitions and motivate riders to join teams.

Stunts Reverse Engineering / Re: Reversing Grand Prix Circu...
Last post by HerrNove - August 21, 2026, 09:55:33 PMGreat find! Developer Roel Derickx had published some initial research on the music (https://github.com/roelderickx/retro-grandprix), but your work is the first one that really documents the format. Also, At Doom's Gate is a really fit replacement for TD2's start menu.

- Skid Vicious will be the great antagonist of this season. He'll race and his times will be published in the scoreboard, so first of all you have to beat him!

Stunts Reverse Engineering / Re: Reversing Grand Prix Circu...
Last post by Swift_ - August 21, 2026, 08:18:01 PMFriendly greetings to everyone from Hungary, it's my first time posting here 
I haven't found any other place online about reverse-engineering GPC, so I registered specifically because I'd like to share my own documentation for the music and voice formats used by the DOS version of GPC and TD2.
You can access the ongoing music/voice reverse-engineering project through this Github link: https://github.com/Swift97/testdrive2-music/
(Don't mind the project name. It started as a SONGS.BIN doc, but GPC's MUSIC.BIN uses the same format.)
It took a lot of trial-and-error experimenting with Dosbox/Hex Workshop/Audacity/FL Studio, as well as a small bit of LLM usage to auto-scan through the GPCEGA.EXE and TD2EGA.EXE files in order to verify/cross-check my findings (especially about the pattern roll's control/event bytes). The result is a documentation that's proven and tested to be effective for both games.
As you can read in the preamble/README, updates may be slow, but I try to update the .MD text files as soon as I figure out something new about the format. I have to juggle IRL matters, other hobbies, work, fooling around with TD2's .PES/Car/Track data, etc. along with this project.
Also please bear with my terrible formatting scheme. I tried to make it as logical and easy to read as I could, but I've never written any docs like this.
I really hope it'll be at least a little useful to someone who might stumble upon it in the future Maybe someone will create a cool Famitracker-like sequencer. Or maybe someone will program a sick original song with arps and pitch bends defined with different voices, perhaps a remix of the GPC theme itself 
Lastly for fun, here's the main riff from Doom E1M1 hand-coded in Hex Workshop https://youtu.be/l2IkhIS0ZVE

Stunts Chat / 4dsL - 4D Stunts League 2027
Last post by alanrotoi - August 21, 2026, 12:41:40 AMI'm working in a new season of 4dsL. Everybody is invited to join the competition in 2027!!
A friend of mine is working with me writing the site automation code thanks to the help of @Cas . If everything goes as expected, the season will start the 1st of January 2027. The 2027 championship will run for a full year and consist of 12 races. We will drive fast racing cars but mainly Porsche March INDY.
I'll keep informing about the progress of the site in this thread. I think we made a good progress on code but it takes time. Meanwhile, I'm working on the site design and in the terrain where the 12 tracks will take place. I made the terrain full map and started to build the tracks. The season will take place in a new continent of twelve consecutive tracks. I attached a picture of the world map below. The idea is to race on tracks designed for specific cars. So we could have different scenarios to race such as mountains, city or coastal tracks.
I have the time, motivation and the workforce.
I'm a little excited about this project, I hope you'll like it too!
