LEGO Rock Raiders Can't Load Missions [Windows 7]

[feckyeslife]

I've been trying to get my copy of Rock Raiders to play on my Windows 7 computer.

 

So far I've encountered the d3drm.dll issue (Solved), had missing AVI Codec files (Solved), needed to launch in compatability mode (Solved), and had missing cutscenes (Solved).

 

My current status is to run in Windows 98 mode with all of the checkboxes for compatability checked off.

I extracted the videos from the DATA folder of the ISO file that I got the game from and saved them in the new DATA folder in my Program Files. For some reason when I installed it, those videos were not moved over.

 

When I try to play the game, I have to play using the RGB Emulation mode rather than the Direct3D HAL mode on the mode select screen. Once I do that, the game launches, shows the LEGO video, shows the little intro movie (which is skippable), and goes to the main menu. Everything loads fine on the main menu. I can go to the Start Game screen or the Training Mission screens with no issues. However when I try to start a mission, eveything crashes and there is no error message.

 

What else do I need to do to get Rock Raiders running?

When the crash occurs at starting a mission, it must be the videos that disturb your computer.

Try this: 

Get that tool and extract the .wad files. 

Then go to Lego.cfg and find the text

DontPlayAvis

It is located somewhere between line 100 and 130. Change the "FALSE" behind that word to a "TRUE". Then the videos should not show up anymore.

Okay, let me guess, you're using a Radeon HD video card on Windows 7 64-bit and the game doesn't start in D3D HAL mode, so you're forced to used RGB emulation, the rockfall transition animation between menus appears textureless (all white) and slows your game down while it plays, and of course, the crashing that is the whole reason you started the thread.

 

If all those things apply to you, there are a good half dozen other threads at least on this topic (and posting in one of those instead of creating yet another thread might have been a good idea) but no one seems to have found a solution yet. The game simply does not work in RGB emulation mode, and D3D HAL mode seems to be incompatible with Radeon HD cards.

 

The only "solution" I've found is to simply switch to a different graphics card, which of course doesn't solve the core issue and isn't at all practical solution for most, since most people don't just have a bunch of different graphics cards sitting around (unless, like me, your CPU happens to have integrated graphics that you could use).

 

Any additional information you can provide can help, but since nobody has found a solution despite the many posts on the subject, the outlook seems kind of bleak, the game just might not be compatible with certain Radeon cards, period.

 

 

Oh, one thing you COULD try that worked for one person at least, is mess around with the setting in CLGen.exe (in your Rock Raiders folder, run it, change the setting, then try launching LegoRR.exe, if that doesn't work, try another setting) to see if that enables you to run in D3D HAL mode. One person in another thread claimed it worked for them but it didn't fix anything for me and not many others jumped in to share their experience with it.

CLGen just applies shortcut parameters to the game. If I remember right, the two options it applies turn on/off the fog and force the game to use practically no memory for textures (I think it turns off all lighting effects, actually). You can edit CLGen.dat to apply the -testlevels parameter, if you really wanted.

Your best bet is to try different settings in the Catalyst Control Center for your graphics card. I had LRR work on a Radeon before, but it ran slowly, so I think it's possible for certain cards.
