Don't start the game via the shortcut, start the game via the supplied "mr.cmd". (Just doubleclick it).

YES! It worked. Thanks 81RED!

BTW, 81RED, would you share the the source code of Bitdepth.exe? I made some utilities for my daughter in the past (they change the size of the screen, the color depth, etc). The problem is that they use DirectDraw, which is pretty unstable and incompatible with modern video cards.

Since I'm using a somewhat uncommon compiler, the source code will not be of much use to you - but its fairly simple and a Google for "ChangeDisplaySettings API" will reveal several places with source code examples. You will find that you can do all sorts of stuff via that API call, in my case I limited it to setting the bitdepth only. :)

I just made a .bat with that:

data\bitdepth 16
game -D3D -CorrectRatioTextures -ZBuffer -nodither -TextureVideoMem268435456
data\Bitdepth 32

and iut works, a .cmd with the same just complained about bitdepth syntax... thanks for the fix, it even works on lame DotEmu's release that I have... thanks~!

I've been going through this thread and have experienced some problems I seem to be alone with.

First, I tried for the longest time to get D3D to work only to discover after a while that the game wasn't as good looking as I remembered. Turning on D3D in options menu gives me slightly less pixelated graphics.

Turning on the "filtered" option removes the distortion in the hud info inside the game.

Now, with D3D turned on I can't seem to turn the bike all the way left or right. Or rather, going into a bend the bike will keep turning but it won't "lie down" as it should. I got the full steering to work once, but I'm not sure if there were any parameters or if I removed them all.
I should state that this is when I try the first coastal course. It behav4es differently when I go to dirt track. There the bike turns fully but when one would expect it to jump it stays glued to the ground.

The other *big* problem is that the game runs way too fast. It doesn't matter if I use the -FrameRateMax0 parameter or not.

Anyone got any ideas about these "problems"?


EDIT: Never mind. I solved by adding -FrameRateMax30. I leave my post unedited though if someone else experience my problems.

It would be nice if the game worked out of the box...

I don't imagine that the fixes posted in this thread actually work for the retail (or in my case OEM with one of the early NVIDIA 3D cards) release... Before I put the work into digging around and finding it, I thought I might see if anyone else knew. I love supporting GOG, but when you already own the game, you kinda want to see if you can make it work first. Thanks to anyone who might know!!

My problem is that i cannot even start the game. I have XP SP2 and when i double click on the icon the message is displayed: application not executed correctly...
The same thing happens with MR and MR 2.
Whats the matter?

EDIT:
OK motoracer 2 works
Motoracer doesnt work
Ill try to install windows 7

EDIT 2
Shortcuts from desktop dont work. You have to go into the game folder.

I just want to thank all contributors in this thread for the solution to de D3D problem. Initially I couldn't get it to work but with the command line parameters and the trick to change the color depth it works flawlessly (changing color depth manually was a real hassle)

I bought the original in 1997 and it was one of my first PC-CD games, I remember getting a Diamon Monster 3D (Voodoo 1 3dfx card) and installing the 3.22 patch and I was blown away by the 640x480 bilinear filtered graphics. Now I can play this like in the old days, a true classic, thanks!

so basicly i buy the game that doesnt work -.-? I bought Moto Racer, and it doesnt run on XP...when i click .exe i have just black screen and nothing. PM me for solutions please

Hello.

If anybody is still having trouble getting d3d to run, you can try this little hack I made. Backup your game.exe first and then unpack all files to the directory where game.exe was located. This hack uses wined3d - which is actually a d3d to opengl wrapper from the wine (www.winehq.org) project. For me it works quite well (except "enter your name" screen but I can live with that).

Note that after you exit the game, game.exe process needs to be killed manually.

I know this is far from perfect, but as proper DX3 support nowdays, depends heavily on video card/driver combination, it can be our only hope.

Of course any modifications you do at your own risk ;]

Best regards.

EDIT:

Hmm it would seem that GOG ate the file... I will provide link shortly.

Sorry to necro this thread, but can somebody update that link?

Hi,

i tried to run Motoracer 1 these days on my Win 7 x64 and it crashes with Direct3D before the Dolphinsoft logo would appear.
I performed a clean install of the latest nVidia driver and afterwards i could play the game with D3D.
Of course, the newer driver weren't the issue on a game from 1997 but if you suffer from this problem you could try to just re-install the drivers.

The polys are all messed up in D3D here. Software mode stutters sometimes. I did notice that if you set the detail option to 1, it looks like you're playing a cool retro game. Plus it runs better.
