Title: OpenTTD 68k SDL error
Post by: motorollin on June 15, 2006, 12:04:47 PM

I'm trying to get OpenTTD working on my A1200. I have copied the TTD data files in to the data drawer, and also downloaded sdl.library from Aminet and copied the library to libs: as I believe this is also required. When I run the game I get the following error:

Error: Unable to load driver sdl(SDL Video Driver). The error was: Found no sufficiently capable CGX visuals

I have P96 and RTGMaster installed so I don't know what's wrong. Has anyone been able to get this working?

I guess this is a P96-related problem. I get exactly the same message when trying Gunnars SDL arcade game on Mediator/Voodoo.

:-( Oh well, guess I'll have to run it on my iBook.

Have you installed the PowerSDL lib ?

Just try to install the very latest P96 (v2.1b, which can be found here (http://amiga.serveftp.net/downloads.html)) and you should be able to run it.  ;-)

That only works on PPC IIRC.  He wrote in the subject line that he's trying to run it on 68k.

@Motorllin

I have this problem aswell even after installing Picasso96 v2.1b and the latest 68K SDL.library I can find

If you get it working could you tell me what library versions of anything ur using please!

SDL.library is useless in this case as OpenTTD is statically linked against libSDL. Since it seems we all have a Mediator here, AFAIR there was a problem with SDL+rtg.library coming with the latest "official" P96: updating to a newer rtg.library should fix the problem.
Could you please try to start it with -d switch (enabling debug mode) and see where it complains?

Hmmm, just updated to the latest version of P96 but it didn't make any difference. The -d option didn't seem to make any difference - I got the same output as I posted originally.

I think zerostress was proposing exactly *not* to use the rtg.library from the latest P96, but to update the library alone to a newer version.

Ok, I guess there's a more recent rtg.librar than the one in P96 then?

Okay, now I seem to remember that even the rtg.library shipped with v2.1b wasn't new enough. :idea:
You need to install a newer one, such as the one you find in this (http://www.haage-partner.de/download/Amiga/AmigaXL/AOSXL-Update1.lha) archive. It should do the trick.

Downloaded that archive and the version was the same. Copied it over anyway and still got the same error :-(

Hi,

I wouldn't bother attempting to run OpenTTD on a 68K - on my 68060-based A3K, it crawls along...

Shame really as it's such a cool game! Some things just need PCs!

 - Ali

EDIT: annoying really, as the original assembly language-based TT and TTD ran fine on slow 486s (25MHz was fine!) but the portable C-based OpenTTD just has too much of an overhead. Anyone fancy coding a native Amiga 680x0 asm version?!  :-D
