norbert_kehrer Posted September 7, 2015 Share Posted September 7, 2015 Hi, similar to my earlier conversion of Asteroids, I made a port of the old, but very nice car-racing game Sprint, which was originally written by Atari back in 1976 (Sprint 2 for two players) and in 1978 (Sprint1 for one player), respectively. I ported the game to the Atari 800XL computer by just running the orignal arcade game program on the Atari. The arcade machine's video and sound hardware are emulated by specific Atari 800 XL routines. The xex and atr files are attached below. You can read more on my homepage at http://members.aon.at/nkehrer Here is a screenshots of the running game: Have fun!

Rybags Posted September 7, 2015 Share Posted September 7, 2015 Nicely done, every bit as frustrating as the original (played in Mame for comparison). They actually had pretty good sound effects on the arcade version, discrete logic/circuits as per many games of the era. Quote Link to comment Share on other sites More sharing options...
oracle_jedi Posted September 7, 2015 Share Posted September 7, 2015 Looks like this is PAL only. The game refuses to start on my NTSC machines. Otherwise this is really fun. Thanks! Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted September 8, 2015 Share Posted September 8, 2015 why would this be PAL only, it started as USA game... I better download it and try to run it.... Quote Link to comment Share on other sites More sharing options...
Rybags Posted September 8, 2015 Share Posted September 8, 2015 These conversions have a sort of emulation layer, usually some translation needs to be done like graphic mapping, controller input and sounds. Generally this means that lots of frame time comes in handy and PAL has a big advantage there. Control input and sound is usually fairly trivial in CPU time terms but graphics can potentially be a huge resource hog. The alternative for NTSC might be like for Yoomp - reduce the framerate. Whether that would work on this game, no idea. Quote Link to comment Share on other sites More sharing options...
griz Posted September 8, 2015 Share Posted September 8, 2015 (edited) Norbert, you do some very nice work. Thanks so much for releasing this to the community. Do you have plans for any other early Arcade game ports to the A8? I see that you also did a YM player for the 64. With Ivop's Sid Player and your software could we could play ST YMs on an A8?

Poison Posted September 8, 2015 Share Posted September 8, 2015 Nice! I play it on real arcade machine in arcade museum:) photo 4 and on the left side:) http://www.arcadehry.cz/index.php?str=9 1 Quote Link to comment Share on other sites More sharing options...
norbert_kehrer Posted September 8, 2015 Author Share Posted September 8, 2015 Hi, thanks to all for the nice feedback. Especially, for the reporting of the issue with NTSC machines. I will try to fix it and post an updated version. I suspect, it has something to do with the VCOUNT register, that I use in my code (it holds the currently processed raster line of the Atari 800, which has different values for NTSC and PAL machines). So long Norbert 6 Quote Link to comment Share on other sites More sharing options...

charliecron Posted September 9, 2015 Share Posted September 9, 2015 There was a little corner store in the middle of my paper route where I would spend all the money I earned on said paper route playing this game. 1 Quote Link to comment Share on other sites More sharing options...
norbert_kehrer Posted September 12, 2015 Author Share Posted September 12, 2015 Hi, I managed to fix the bug with the VCOUNT register. Now the game should also work on NTSC machines. I could only try it in the emulator, though. You find the updated atr and xex files attached. Thanks again to all for your feedback.

Mclaneinc Posted September 12, 2015 Share Posted September 12, 2015 No, Norbert, thank you for such a great port...I used to play this in the local fish and chip shop as a lad.. 1 Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted September 13, 2015 Share Posted September 13, 2015 Works perfectly, in fact the enemy racers are super fast.... game had steering wheels, perhaps drive controller or paddle candidate.... multijoy candidate? I just played 3 games but did not test much further.... I got my ntsc butt handed to me! gas..... up to shift left right right right oh crap crash! I will win... I'm going the distance... I'm going for speed! this kicks a** Nice job Quote Link to comment Share on other sites More sharing options...
+Philsan Posted September 13, 2015 Share Posted September 13, 2015 It would be nice to add support to Atari Driving controllers. 2 Quote Link to comment Share on other sites More sharing options...
ACML Posted September 13, 2015 Share Posted September 13, 2015 It would be nice to add support to Atari Driving controllers. Awesome game. Thank you for the excellent game! I too second the notion that a paddle or racing controller would make this even better. 1 Quote Link to comment Share on other sites More sharing options...
robc Posted September 13, 2015 Share Posted September 13, 2015 Had a quick spin of this under emulation - this is pretty darn awesome. Nice work in putting it all together. Can't wait to copy it over to my XL and give it a spin on proper hardware when I get a chance. Quote Link to comment Share on other sites More sharing options...
kenjennings Posted September 13, 2015 Share Posted September 13, 2015 It would be nice to add support to Atari Driving controllers. Ditto. Super idea. 1 Quote Link to comment Share on other sites More sharing options...
Gury Posted September 14, 2015 Share Posted September 14, 2015 Very good and frustrating game in positive way, of course. I checked your site, where I see you also develop for other platforms, very interesting list of products. Thank you for all your ports.

+MrFish Posted September 14, 2015 Share Posted September 14, 2015 (edited) Sprint 4 is a pretty cool incarnation of this game too. It doesn't have the oil slicks, but it uses larger, colorful single color car sprites, and it's a little more fair dealing with collisions, in that the opponent drivers will lose control when they hit or get hit by you as well. It looks like it was designed in cocktail mode and has 4 player support too. So probably the reason for having the fairness in collisions, but it does so even when no human opponents are playing.

+therealbountybob Posted September 19, 2015 Share Posted September 19, 2015 Nice work again Norbert This is bound to feature in the High Score Club at some point this season but first I must do something about my Granny rating... I have a reputation to uphold perhaps the cars images could be tweaked at some point. I remember playing this or something very similar at the arcades but didn't remember the track changing after each lap Quote Link to comment Share on other sites More sharing options...
