Sorry I'm not planning on developing a Mac OS version, but the Windows source code (including the Amiga 68000 source file) is available here: https://sourceforge.net/projects/stuntcarremake for anyone who fancies working on it.

Yes and no - I disassembled the entire 68000 code on the Amiga, then spent a while studying and commenting it. Then I wrote the new version in C/C++, using the Amiga algorithms for the car physics.

Yes the sound is original and the binary data was taken from the Amiga then converted to .wav files for playback under Windows. The only thing missing is the Amiga's low pass filter!

Thanks. Unfortunately I tried and failed to alter the car's physics code to handle 60fps. The Amiga routines that the new code is based upon were written for the Amiga's frame rate of 8-9fps and when I tried to change them (e.g. by reducing various constants and variables) the physics was just all wrong (e.g. the car would no longer jump sufficiently).

Again the Windows source code (including the Amiga 68000 source code) is available here: https://sourceforge.net/projects/stuntcarremake for anyone who fancies having another attempt.

Not sure if this is what you're after, but there is a 'speedrun' version for classic Amigas somewhere, which was created by someone else and allows for a much faster frame rate on more powerful Amigas. (The original Amiga version had a frame limiter in the code to ensure that six vertical blanks had occurred between frames, giving a frame rate of 50/6 = 8.33 fps. The 'speedrun' version either removes or significantly reduces the limiter).

Thanks for the positive comments and for featuring the game on your web site too.

Remember you can press the F10 key one or more times to slow the game down if needs be (and F9 to speed it up again)

Thanks. (Try pressing the F10 key

This is the coolest thing i've seen in a long time. I've been lurking on eab for a very long time but have never needed to join. But today I had to join eab just to let you know how awesome and cool you are djvernon!

Releasing the c++ source AND the 68k source is just too much, the most i ever disassembled in the old days was 250kb - but 450 kb of 68k source?!! that is real dedication.

I have written quite a few 3d graphics engines and would encourage you to try doing an OpenGL port, since you are not using multi-textures or pixel shaders etc there should be a 1:1 correspondence between most direct x features and OGL ones and it would be alot of fun to learn and the game would then work on a range of platforms.

I'd also encourage you to add multiplayer/network play. In the old days my friend would come over and we'd connect his ST to my amiga and play Stunt Car Racer multiplayer for hours instead of studying for school. I can imagine how much fun it would be to start up a Stunt Car session at work on the local LAN after a Friday afternoon pint and have 8-16 people all trying to get the fastest time and knock the others off the track!

Once again kudos to you, most people are pure talk when it comes to projects like this but very few will see it through to release, well done! :-)

I played it for 2-3 hours, here is some feedback: the physics is almost perfect but the "stepping stones" seem harder than the original - you have to be more precise on the win32 version, however I last played stunt car racer perhaps 20 years ago and may have wrong memories!

One thing you could immediately do to improve playability is not restart the player in between the two "arms" of a ramp if they crash on a ramp/jump. similarly in the original if you crashed on a ramp/jump, you would always be restarted at a position that would give you sufficient "run up" to get over the ramp.

Next priority could be to get the "push up/forward to accelerate, firebutton for turbo" functionality working, because i think in the win32 version the only way to go forward is to burn turbo?

Thank you djvernon for many hours of fun! :-D

As a Linux user I'm happy to report that it seems to be working well with Wine (1.5.4) on Ubuntu 12.04.

Great work!

@djvernon: which is the 'speedrun' version out of all of the ones listed below found at the http://thegamearchives.net/:

Stunt car racer (1988)(microstyle)[h][t +2 enigma][stunt car racer turbo]-amiga
Stunt car racer (1989)(microstyle)-amiga
Stunt car racer (1989)(microstyle)[a2]-amiga

Stunt car racer (1989)(microstyle)[cr qtx]-amiga
Stunt car racer (1989)(microstyle)[cr woodpecker]-amiga

Stunt car racer super division (1989)(micro style)[miami bass][cr defjam]-amiga

I want to be able to play SCR where it's SMOOTHER at 60fps (but not faster), and with the original physics.

My version

twinbee · 18 March 2016, 11:36

Ah nice.

I tried it though, and pressed F3 for turbo mode. Unfortunately, it's mega-fast

Any fixes for that? I want it at normal speed and smooth.

s2325 · 18 March 2016, 13:18

Try choosing slower CPU if you are using WinUAE.

twinbee · 18 March 2016, 13:51

Yep, I tried changing the CPU speed to -70% in WinUAE, but then frame rate drops again down to 15-20fps. I want it to run slow and smooth simultaneously.

s2325 · 18 March 2016, 13:56

-70? Maybe just use 68020 without any additional options.

Steve · 18 March 2016, 18:27

I tried downloading the source code but it only downloads the zip with the game only. Anyone have the source code version?

Michael Sykes · 18 March 2016, 22:03

Nice remake.
What about controller support fullscreen and some decent FX for some events?
That would make it complete.I hope to see a polished version of that game.
Maybe in some appstores so we can run it on all kind of devices.
But I bet someone else still has the copyright...
And btw, I used nvidiaInspectors framelimiter to play at 60 fps.

Okay, basically, on first playing, it does run at normal speed. The problem is when I press F3, the game runs WAY too fast. So I tried to compensate by turning the CPU speed down. But then we get back to slow and jerky.

I want it slow (normal speed) and silky smooth (50/60fps) at the same time. Is this even possible - can anyone claim that they've successfully managed to do this?

Not possible without modifying the physics code, cf this thread.

Nice work! I'm a big fan of the game! Glad to see it getting love!
