If anyone is still having problems with the game lagging and crashing, just follow these instructions;
1. Download the file from this link (
Google Drive)
2. Open your file manager and go to C:\Windows\SysWOW64
3. Scroll down until you find the d3d9.dll file and rename it d3d9.dll.old (this will make the file unusable but don't worry, but whatever you do, do not delete this file, maybe make a backup and put it somewhere safe)
4. Once the file has been renamed, take the d3d9.dll file that you downloaded and move it to C:\Windows\SysWOW64
5. That's it, the game should work fine after this (Fun fact, this will also make other old 3D games work)
If you find that you can't rename the d3d9.dll file then you'll need to change the file permission, should be pretty simple but if you struggle with it just send me a message and I'll write a short guide on how to do that.
