Sprint 1 ported to the Atari 800XL

Recommended Posts

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.

Here is a screenshots of the running game:

Have fun!

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.

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.

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?

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

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

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.

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.

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.

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.

Nice work again Norbert :thumbsup: 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 :-D 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 :ponder:
