Open Transport Tycoon ported to Dreamcast !

[Christuserloeser]

New forum member stevenh ported Open Transport Tycoon Deluxe, an open source clone of Chris Sawyer's Transport Tycoon Deluxe from 1995, to Dreamcast:

So, after a few grueling weeks of screwing around with the KOS libraries (KallistOS) I managed to compile and run the latest revision of OTTD.
It's been more of an educational experience than anything else and runs like crap [at around 70% speed] (the 200mhz SH4 CPU seems to struggle) but it's been a lot of fun...
I have CD images in DiscJuggler format (self-booting) of the latest version but due to dependencies that don't exist off-the-shelf I don't think this should ever be included in the trunk... I mean, does anyone still have DC with Mouse and Keyboard?
... on that note, the controller can be used... but it's not as much fun.

You can download the CDI here: http://www.otenko.com/dreamcast/OPENTTD-DC.cdi

the learning experience is what is important, so dont get discouraged about slow speeds. Thanks for the port.

Still working on it, it seems:

Update (as of 3rd December..)
Rubidium has been doing some more great work ... a lot more solid than my hacking around... we've added a lot of support to the OpenTTD codebase to interact with the KOS build tools to the point where the command-line arguments are minimal and compiling is a much happier task.
With the kos_v2.diff patch seen here and this command-line:
$ LDFLAGS="$LDFLAGS romdisk.o" ./configure --os=KOS --cc-host="kos-cc" --cxx-host="kos-c++" --with-sdl --with-png --endian=LE --personal-dir="/rd" --install-dir="/rd"
You'll nearly get a working version... apart from the romdisk which you'll also need... so this update is pointless until I sort that out
Stay tuned...

Pretty sweet work, stevenh. I'd love to see this running at full speed.

How completely random...

I was just digging through my blog and saw that there were quite a few references from dreamcast.es... So I went to the site and saw the post of my efforts... then saw this link and realised I'd gained coverage everywhere!?

The original CDI is on my site... but I can't get it to run in nullDC, DEmul or Marakon... but the anonymous comment poster tells me it runs in Marakon on his Linux/Mac? machine and also lxDream.

Either way, the attempts to re-port it gained some momentum... but I'm at a point where Rubidium on tt-forums said it worked but I can't get anything going locally... as you can see from the screenshot above I used to use DEmul, but that wont work anymore...

If people could post success stories (and then tips on what bios/flash/emus they used) it'd be greatly appreciated
