Patching Lego Universe to not crash in wine

bgstack15

Comments

The old non-free OS game Lego Universe runs moderately well in Wine. However, it does tend to crash with errors like the following.

0138:err:virtual:allocate_virtual_memory out of memory for allocation, base (nil) size 00100000

Usually when entering a different region and the game is clearly trying to load all the assets for this region. The game will freeze up for a second, and then crash. What solved the errors was using a 4GB Patch – NTCore utility that patches the binary headers so the program can address more than 2GB of RAM.

That was it! This small program works in Wine. You pass it a binary name to patch. I backed up the file, of course, and the differences are very small.

I tried winetricks d3dx9_43 but it didn't help. I then realized it uses d3dx9_34 but that didn't help either. I tried using wine first, then native, but that breaks the game and rendering even on the login screen.

I also tried winetricks dxvk which also added d3dcompiler_43 d3dx9 d3dcompiler_47 dxvk but this completely broke the game. So I reset my wineprefix afterwards.

I didn't record where this came from, but this didn't help.
